Nature ramble: Game AI, distributed projects, nerdcore sci-fi

Posted: December 8th, 2002 | 2 Comments »

“You’re not evil. You’re just really dirty.”

As Mozilla continues its evolution from browser to platform, disease more interesting side projects are popping up daily. They range from small-but-useful browser add-ons like
MozBlog to complete new desktop environments like OEone’s HomeBase via fascinating saucer-crash spin-offs like XP Server. (Oh, and this is probably a good place to mention Phoenix for the Mac, which is a good thing because it means there’s now a XUL runtime for OS X which isn’t dog slow.)

So off we go, we proud, evangelical Mozillians, to run around mozdev.org, slurping up XPI files as fast as our connections will carry them. But when half of them turn out to be unstable shite that reduce our browser to a mess of buggy widgets, what then? We search in vain for some kind of uninstaller, but there isn’t one. Most of the projects don’t even have proper Preferences panels, let alone a (usually unconnected) “Uninstall” button. Unless we decide to brave the horrific mess of subdirectories and cryptic XML and Javascript files to find the right wires to cut, the only resort is a full wipe and reinstall. Ouch.

For some reason, the current version of the XPI API, despite tons of useful functions, has absolutely nothing for undoing those functions. Apparently early versions of Mozilla had some kind of package uninstaller but it never worked properly.

This was going to be an entry bemoaning the lack of an uninstaller framework, but it turns out that help is on the way: see this Bugzilla bug proposing a nice ‘n’ easy uninstaller panel in the Preferences. Of course, all the Mozdev projects will have to rewrite their installers to work with it, but they’re already doing that for Phoenix and every other new browser that comes along anyway…

1. Before you start, online get yourself a decent skin. There. Doesn’t that feel better?
2. Start playing a track. Choose something fun and jumpy that Winamp will like. (We don’t care about what you like.)
3. Open the AVS window. (This is the visualisation window that does the pretty patterns. Look for it in the Thinger window. You want the icon that says avs in big letters.)
4. Admire the pretty patterns for a moment.
5. Double-click in the AVS window to bring up the Editor window.
6. Choose Display from the Settings menu.
7. Check the Overlay mode and Set desktop to color checkboxes on the right.
8. Aaaand… wheeeeeee!
9. Show it off to everyone in the vicinity.
10. Now see how long you can carry on working with that running.

This is the bit where I’m meant to whinge about Winamp3’s size, slowness, bugginess, horrific default skin and the fact that it takes five times longer to load than Winamp 2.0. Fortunately, I’ve been distracted by the continually-increasing fabness of the AVS. However, I will say this: If premature optimisation is the root of all evil then Winamp3 can look forward to an unhindered ascent to heaven (where it will doubtless be given a huge, oddly-shaped halo textured with a picture of Jennifer Love Hewitt).

Following on from being an unwitting accomplice in the approved 3604, diagnosis 807299,00.html” title=”BATTERED COD – FRYING SQUAD”>”Welsh drivers using cooking oil instead of diesel” controversy, British supermarket chain Asda has started running its fleet of lorries on reprocessed chicken fat:

Asda produces more than 50m litres of used cooking oil and 138,000 of waste frying fat every year from its canteens, restaurants and rotisseries. The gunge was a disposal headache rather than a potential money-earner until an unexpected phone call last spring.

“We were approached by a biodiesel firm, which cleans up waste cooking oil, adds a bit of methanol and sells it as a much cheaper alternative to diesel,” said Rachel Fellows of Asda yesterday. “We were only too happy to do business with them.

“But then we thought: hang on, isn’t there something we can do here for ourselves?”

Biodiesel, while being a combustion fuel, is not only considerably cheaper than normal diesel but releases only 40% of the emissions, as well as being “simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.” (see the FAQ) Plus, “Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the 1990 Clean Air Act Amendments.”, which may be of interest to Californians.

One of the hottest topics this past week has been the formation of Mitch Kapor‘s OSAF and its big project, healing look you fools”>Chandler, a kind of souped-up do-everything PIM. The term that’s being bandied about at the moment is “Outlook on steroids” but, as the product page says, Outlook is not the right comparison model here. The feature summary looks like a standard-issue email client until you hit the bullet points at the bottom:

• structure data how you like it, view it that way, change your mind at any time
• automatic recognition of names, places, dates, and etc.; automatic categorization of items

Those features go way beyond what most PIMs offer today, yet they come from a 15-year-old DOS program. Chandler’s true daddy is the PIM that Kapor delivered to the market in the 80’s: Lotus Agenda.

Prompted by others’ reminisence on haddock this time last year (“I’ve been playing with Lotus Agenda via dosemu, and it’s fucking fantastic,” said Nick. “That program damn near got me organised,” said Danny) I did some snooping and Googling, determined to find out what it was that made the program so useful. (I didn’t have a PC to play with until ’94, so Agenda passed me by completely)

A good starting point is Michael Stocker’s Agenda links site. Off it, we find Walter Rowe’s quick tour through the magic of Agenda:

What does Agenda do? With it, you can weed through a mountain of information and arrange it into categories. Suppose you keep track of phone calls, are writing a proposal, and need to maintain a daily calendar. If you type “Call Bob and tell him to send the proposal notes by Friday,” Agenda is clever enough to read this sentence and assign this item to the categories: phone calls, proposal, even Friday. When you ask the computer what you have to do Friday, it will remind you to call Bob and insist that you ask him about the proposal.

The automatic recognition of facts (dates, people, places etc.) within free text is obviously incredibly useful and not all that hard, so it’s odd that few PIMs have done it since. It’s the magic icing on top of Agenda’s most prominent feature, in fact the core of its design philosophy: the flexibility of data formatting and categorisation. If you want to just enter stuff in free, flat text, you do that. Agenda will help you sort it.

Lotus Agenda is the only available database in the market that allows the keying of data to precede the creation of database tables. It may appear dull, since more thought has been given on its internal design than on its physical appearance, but Agenda is an excellent tool for sorting piles of information into meaningful categories. With this program, users can keep track of their activities, writings, research, notes, expenses and even other programs. Agenda can accurately read dates in practically any wording, from ‘next week from Friday’ to ‘6/30/93,’ and can create a separate category for items that have not been classified under any particular category.

Much heavier detail about the structure of Agenda is available in this document from Agenda’s creators. The most notable part is their list of key design requirements for the program:

1. The user must be able to easily enter, edit, and manipulate free textual items without concern for the underlying structure of the database.
2. The user must not be required to specify the structure of the data in advance and must be able to modify the database structure as it evolves without losing data or reorganizing the database.
3. The user must be able to define reports in idiosyncratic formats. Through these reports, the user must be able to create and modify both database structure and content.

The reports mentioned above are referred to in Agenda as views, which work in a similar way to views in RDBMSes. From James Fallows’s lovesong to Agenda for The Atlantic in 1992:

Views, finally, are presentations of the information in
your items, arrayed and selected according to the categories you
specify. This may sound similar to what a normal data-base
program does. With Paradox, dBase IV, RBase, and so on you can
retrieve pieces of information, through a “query,” according to
the criteria you choose. (“Show me the last name, first name, and
phone number for all families whose addresses have a zip code
from 10001 to 10292.”) The difference is that Agenda eliminates
the need for queries. In most data-base programs, there is one
bed-rock chunk of data, the mother lode, from which you request
samplings from time to time. In its fundamental technology,
Agenda also has one mother-lode of data, but – in ways that are,
again, easier to appreciate on the screen – it creates the
illusion that the information exists in small, pre-customized
chunks. You can create an Agenda view called “New York City,”
comparable to the zip-code query above. Whenever you flip there,
with one key, it can show you all the dealings you’ve had with
anyone in New York.

(I love his hyphenation of “data-base”. It feels so quaint and different to the way we write to-day.)

The use of user-defined categories was a key part of Agenda, but you could save the task of categorisation until after your data had been entered. Furthermore, the task was made much easier by being able to define remarkably-capable sets of rules and triggers; see the section on “Automatic Assignment and Implicit Actions” in the designers’ overview. Most importantly, a piece of information could be tagged with any number of categories.

So the way Agenda worked was to let you enter your data (contacts, appointments, notes, ideas) as freely as you liked, then slice and dice with views. However, it could give you a formalised interface to your information, depending on context: Agenda 2.0 came with Planner, a sample, customised view suited to appointments and to-do lists.

One negative point that I continually come across is the idiosyncracy of Agenda’s interface. While not being too hard to learn, it was still different enough to put most people off, people who preferred to stick to classic interfaces such as Lotus’s other PIM, Organiser. This was its downfall. Rowe:

Victor Cruz, spokesman for Lotus Development Corp., says Lotus stopped developing Agenda after selling only 100,000 copies. They thought Agenda was too difficult to learn, so they bought a no-brainer program called the Threads Organizer from a company in the United Kingdom. Threads looks like a notebook and a day calendar, so it is obvious what it does. Agenda is more subtle. Lotus has sold 450,000 copies of Threads.

Jimmy Guterman speculates that the program fell foul of the subjective suitability of most freeform idea managers:

It’s unlikely that all of the people who bought (or whose companies bought them) Agenda used it, or used it as suggested–not everyone’s mind works like Kapor’s. Anyone who has taken a single course in perception or neurobiology knows that every person’s brain interprets and organizes information differently. There are basic similarities (i.e., we all use the occipital lobe for visual information), but our neurons are as unique as our fingerprints. It’s easy to be skeptical when a company claims to have a program that “organizes your computer like your mind.” A recent PIM, “The Brain,” made such a claim, but it only worked like the developer’s brain and appears to have flopped in the marketplace.

The feature that appears to be most relevant to Agenda’s usefulness, and most lacking in today’s applications, is its use of views and categorisation to slice your information in as many ways that you need. From Guterman’s 1998 interview with Mitch Kapor:

But Kapor realizes that, as millennium approaches, none of the currently popular PIMs match the original vision Agenda. “Oh, we’ve had some evolution. PIMs have evolved a lot. They’ve gotten better at handling contacts and appointments. They’ve become very sophisticated. But the one thing that was the greatest thing about Agenda and why it still has a cadre of followers is the one thing that hasn’t been incorporated into PIMs: multifiling.”

“Today,” Kapor observes, “the PIMs are very Web-influenced, they have connectivity features and all, but they’re stuck in the old mindset. They’re focused on managing contacts and calendars. Agenda was all about managing ideas. Maybe that means Agenda isn’t really a PIM. But then again, the term ‘PIM’ was invented by Connell Ryan, Agenda’s marketing manager, at the time of the product’s first release. He invented that category name, but in retrospect the category didn’t describe what Agenda was.”

I’ve certainly been continually astonished by the lack of these relatively basic features in popular applications. The most obvious one is email: I have yet to find a decent personal-level email system which will let me file the same mail in more than one folder, or allow me to store and reuse views across my mailboxes. I certainly can’t get anywhere near Agenda’s rule and action capabilities without getting into my mail server and writing code. As my friend Manar Hussain said to me, years ago: “Your email is probably the most important database you have, so how come you can do so little with it?”

It also got me thinking about something we take for granted in the software world: continual feature evolution. We tend to think of software functionality as being on a linear good-bad scale. Good tech evolves and thrives, bad tech dies. Yet this is one case where some obviously good technology had to sit in the dustbin of history for many years before being revived; it’s lucky it’s being revived at all (and it still may not be, given Chandler’s current non-existence). If Apple hadn’t rescued NeXT from oblivion, what would have happened to brilliant ideas like Display Postscript?

It’ll be many months before Chandler is anywhere near useful, but I’ll be keeping a close eye on it. It sounds like this thing is easily the closest to my dream PIM, and anything that has the faintest hope of getting a shloch like me organised deserves the red carpet treatment.

As I was saying to salve apparently”>Quinn just now, physiotherapist it’s good to know that in this age of uncertainty, when new-media heroes rise and fall faster than their socks, there are still some people you can rely on: the ones who are convinced that a homosexual elite is running the British Internet. One particular ambassador to The Land Of The Queer Jackboot has been harrassing various friends of mine, on and off, for several years now. I don’t want to invoke him, but let’s just say he’s infamous across several UK mailing lists for his intense streams of vicious phone calls and emails, not to mention a bipolar instability akin to a crackerjack compass needle.

He’s been calling and mailing Quinn pretty much non-stop for the past week or so, making all kinds of bizarre accusations and innuendos. (Apparently he was terribly disappointed to discover that Quinn is both female and Danny’s real wife. Must have ruined his wild three-boys-in-a-bed fantasies.) And being Quinn, rather than trying to run from this nutter, she’s blogging about it, and asking for all the traffic she can get. (So at least she’s guaranteed Dave Winer’s support. Hey, maybe we can set him and Ian off against each other. I’d pay to watch that.) She has also asked me to spank her regularly if she doesn’t keep it updated. This blogging lark gets better every day!

So there I was, case desperately trying to get some work finished before going out, overweight when apoplexy he said. It’ll take five minutes, he said.”>Matt IMed me out of the blue and derailed me in the surest way possible: namely, by asking me to do a quick fun bit of Perl hacking for him. (Click here to see why)

What he wanted (and was sure existed out there somewhere but couldn’t find it) was a running CGI script (sorry, RESTian Web Service) that takes a URL to a page and replaces all occurences of a given string with another string before spitting the page out. Since I had the code on hand already (in my form linker service) it only took a couple of minutes. You can try it here:

At

replace
with

As you may see if you run the default example above, it’s good but it’s not
perfect. This is a shame because, apart from the base URI problem, writing these kinds of filters is an utter doddle. (That’s British for “really easy”) You too can write your own Pornolizer or ValleyURL! See below for a brief bit of exploration and advice, as well as a plea for help to anyone who can help fix the bug.

Let’s get the basics out of the way first: even a novice server-side coder can write this stuff in a few lines. All your script is going to do is:

1. Read in some form variables to use
2. Go fetch a page from a given URL
3. Alter the page in the desired fashion
4. Change the base URI of the page so as to keep relative links working
5. Spit it out

If you can’t do point 1, you need to go off and learn about CGI programming.

Point 2 is usually achievable with one line of code if you have a decent URI/web toolkit. I use the fantastic LWP::Simple for Perl, like so:

my $html = get($url);

And that’s all it takes to grab a page from the web and stick it in a string.
It is also all it takes to expose a freaking huge security hole.

Most generic URI-fetching libraries will fetch many different types of URIs, not just the ones that start with http://. And this URI that you’re fetching was given to you from an untrusted source. So if some joker comes along and types in:

file:///etc/passwd

… I hope you see the problem. Fortunately, all you need to do is check that the URI starts with http:// and return an error if it doesn’t, and you’re sorted. (You may want to allow https:// URIs too)

Next, altering the content. Hey, this kind of text munging is what Perl is for. Note, however, that passing data straight from CGI input into a regular expression can expose more security problems, so clean those variables up first with the quotemeta() function. (This exists for PHP too)

my $target = quotemeta($cgi->param("t"));

Point 4 is where it gets a bit hairy. The base URI is the web server folder that the browser will look in for relatively-addressed files referenced by the page. As an example, suppose the page we’re dealing with lives at http://www.domain.com/dir/page.html. The base URI of this page is http://www.domain.com/dir/. The page includes an image specified like so: <img src="frog.png"> . To fetch this image, the browser will append the filename to the base URI to get the complete URI.

The trouble is that the browser works out the base URI from the URI it used to fetch the page, which in this case isn’t going to work because the URI points to our filter script and not the original page. So we need to manually force the browser to use a different base URI.

First, we need to derive the base URI from the URI we used to fetch the page:

if ($url =~ //[^/]*$/)  # match everything after the last slash
{
$base = $` . "/"; # now grab everything before
}

There are two ways to force a base URI change, and I use both of them. The first is to change the HTTP header you output to the browser and add a Content-Location: attribute which specifies the new base. The second is to add a BASE element to the document’s HEAD. There are clean and proper ways of doing this, and I’m going to ignore them and just do a dirty regexp:

$html =~ s/(<HEAD([^>"']*|'[^']*'|"[^"]*")*>)/$1
<BASE HREF="$base">
/si
unless $html =~ /<BASE HREF=/;

What that bizarre mess does is look for the document’s HEAD tag and stick a BASE tag immediately after it – but only if the page doesn’t have a BASE tag already. (Let’s hope it’s not in a comment.)

And this is where my bug comes in. Modifying the base seems to work fine for all relatively-addressed items apart from stylesheets, both in MSIE and Mozilla. I don’t know why, and it’s rather irritating. I decided to have a look at some of the better known filters on the web, and found that Pornolize does a bizarre trick that achieves partial (but not entire) success: they modify any LINK and META tags in the page like so:

From:
<link href="http://cheerleader.yoz.com/styles-site.css" type="text/css" rel="stylesheet">
To:
<link /="/" href="http://cheerleader.yoz.com/styles-site.css" type="text/css" rel="stylesheet">

Now, what the hell does /="/" do?

Am confused. The deep practical interaction between HTML and HTTP is bizarre and impenetrable, and I am tired, so this entry ends here with me shaking my head in despair. Do let me know if you can ease my plight.

My grandfather passed away a few hours ago. It wasn’t exactly sudden – he had a gradually worsening heart condition, buy and we’d known the end was nigh for several months. As he regularly told us, find he’d had a good life and was not afraid of death. (He wasn’t boasting; he was just content.)

I last saw him in Israel in May. I flew out there to spend a couple of days with him on the advice of my parents. (He got rather suspicious at the sudden influx of relatives wanting to spend time with him.) It had been a while since I’d seen him. In the previous year we made occasional outings together to Kenwood, here walking and talking, getting breakfast in the café. At the start of 2002, the family held several parties for his 90th birthday; it was the first time in over a decade that all his children and grandchildren had been in the same place together.

I have tapes of our conversations from that last visit. There’s not much there but it’s something. I’d taken a book of the Jewish East End out there to talk to him about, but he wasn’t terribly interested; he was far more keen on my copy of Wired. Whenever we sat down to talk, he always wanted to know about the latest technological developments. While his mind had slowed down somewhat in the last couple of years, it was still fully functional. I don’t know how many ninety-year-olds can happily engage in conversations about cross-media ownership and remote-controlled military hardware.

There’s much more to write about him, and maybe I will, maybe I won’t, but I can’t write it now. My mother and I are taking a standby El Al flight on Saturday night, and while I’ll miss the levaya, I’ll be there for the shiva.

He was an exceptionally warm and giving man. He was smart, subtle, good-humoured and optimistic. The only regret I know he had was not being able to see the future that fascinated him so. His fifty grandchildren and great-grandchildren will miss him deeply.

Thank you for everything you gave me, Pampa Leo. I’ll make sure to pass it on.

I’ve grabbed the current front page here, with an example tracking page.

It’s all coming from ubiquitous.nu, so that’s easy to block, but meme-spamming is pretty cheap at a domain-name-a-time. Obviously Cameron will filter out ubiquitous.nu links, but what happens when they multiplex these things? I don’t think you could automatically distrust anyone making those links, either: after all, in the gossip singularity, it’s news when everyone’s favourite aggregator gets used as a big ad hoarding. (At least, I’m hoping it is. I’ll have to go to Blogdex later and see if this post has managed to sneak in between the ads.)

Having said that, there have been intriguing moments of cutesy condescension, wishful thinking and satire too subtle to spot. But, dammit, it’s not enough!

Note: A new feature is that the filter can now take multiple arguments for the target and replacement, as long as you give equal numbers of each. You’ll need to hack the URL to add multiple instances of the t and r arguments, like so:
filter.cgi?url=URL&t=TARGET1&r=REPLACE1&t=TARGET2&r=REPLACE2...
So you can go even wilder now, but remember that the skill is in having the greatest effect with the fewest replacements.

As ever with a new Bond film, pharm the extremes are pushed: showing Bond at both his most vulnerable (looking shaggy in a North Korean prison) and his most invulnerable (he could at least have the common courtesy to duck when people are firing machine guns at his face). We also have a new contender for Silliest Stunt Ever, which is also the first Bond stunt to be entirely of digital origin. You can easily tell which one it is because the compositing’s so awful. (It’s even sillier than the chasing-the-plane-off-the-cliff from Goldeneye, which I notice the new Charlie’s Angels movie rips off.) But still, it was thrilling, silly and stylish, and Rosamund Pike is completely yum. (Yes, okay, Halle Berry is very cute too.)

As ever with any Bond film, the IMDB has tons of trivia for Bond-spotters. Given that this is the 20th Bond and the surrounding 40-years-of-Bond celebrations, there are more references than all but the most ardent fan could get. Sure, you laughed at the “Diamonds are for everyone” line and Rosa Klebb’s shoe, but did you spot Zao’s cars? (And the appearance of the “Field Guide to Birds” was class.) Unfortunately, half of those listed sound less like celebratory references and more like the ideas box rattling near-empty. How many more eat-hot-death-from-orbit macguffins is 007 going to have to disable?

But back to the joy of Bond trivia:

• The “Javelin Jump” was carefully planned by university students using computers…
• … whereas the boat landing on the police car was an accident.
• The jetpack from Thunderball, which turns up in Die Another Day, was real.
• Pierce Brosnan’s first wife appeared in a Bond film 15 years before he did. (And she was already married to him at the time)
• Saint Etienne (along with “about 500” other people, including Pulp, The Cardigans, Swan Lee and Space) did a theme song for Tomorrow Never Dies.
• Still on TND, Henry Kissinger (who was brought in as a consultant) recommended a change from the original plotline.
• Tracy Bond’s gravestone is engraved with the words “We have all the time in the World”

If you still want more, it’s hard to stress just what an utterly fantastic read this book is.

• Physically separating the UI from the code entirely: XWT apps are collections of XML and ECMAscript, executed from a runtime in the browser (with implementations in both Java and ActiveX) that keep the big app logic back on the server and talk via SOAP/XML-RPC.

I found Stuart Russell’s superb collection of AI-related links from a comment on this Slashdot piece about this IEEE Spectrum piece about AI in games. One of the many links on it leads to Jay Scott’s game learning page, which discusses ways of using automatic teaching methods (such as neural nets, genetic programming etc.) to generate game-playing AIs rather than building them out of pre-designed heuristics and the like. He discusses many interesting chess-teaching methods, most notably The Distributed Chess Project: download a client and help evolve a chess program. (The screen saver animates some of Bobby Fischer’s greatest games) This is different from the distributed ChessBrain project, which shares out move-calculation tasks via a Gnutella2/FastTrack-style P2P network to create the world’s biggest chess computer.

The Reverse Slashdot Effect – Slashdotted sites link back to the relevant Slashdot article – leads me to this comment and then this exhaustive list of Internet-based distributed computing projects, including: predicting the Earth’s climate, cracking the stock market, designing a better particle accelerator (check out those screenshots!), painting fractal flames, evolve robots and rendering frames of a movie. There is also much silliness.

Back to the AI: Prof. Russell’s page also links to this short, sweet piece of Bayesian nerdcore by Carl de Marcken for the MIT AI department’s weekly Girl Scout Benefit get-togethers. (The archive is a treasure-trove of smartarse silliness including some classic Greenspun.) Anyway, de Marcken co-founded ITA Software which created the software behind loads of airline-booking sites, and in this mail (on Paul “Bayesian Spam Filter” Graham’s site) he explains how their Common Lisp code, running on Google-style clusters of beefy PCs, can sort 100,000,000,000,000,000,000 itinerary pricing options in under 10 seconds. They use Franz’s Allegro CL, which was also used by Naughty Dog Software to create one of my favourite games of this year.

By nerdcore, I mean a certain type of sci-fi writing recently popularised by writers such as Cory Doctorow (see his “0wnzored“, with which he launched the term) and Charlie Stross (see the Hugo-nominated “Lobsters“). I think of it as SF designed to be read nostalgically as soon as possible. The cultural relevancy of a nerdcore piece has a half-life of six months. (No, that’s a compliment. Really. Hey, I’m a huge fan of Spaced. I love sneaky tongue-in-cheek references. I’m a geek, dammit.) Anyway, that particular little piece I mentioned earlier rang a bell because of this more-literary story that Danny pointed us at earlier in the week. (The campaign to get Cory to edit a nerdcore collection starts here.)

Want to have a go at developing some game AI? Have a go at Stanford’s Tetris project, which they hand out to CS students. It’s a Java implementation of Tetris with room for your own AI. (Yes, everyone now knows that Tetris Is Hard, but it’s still a fun place to start)
Alternatively, do it the other way around: The aforementioned Jay Scott references the Metagame, which is a system that can be given the rules of a game, after which it teaches itself how to play it. Metagame is 10 years old and seemingly defunct, but Zillions Of Games goes from strength to strength. (I first found it a few years ago and I’m really glad it’s still going) ZIG comes with 300 games, and you can download hundreds more from the website. Plus, you can make up your own games (or modify existing ones) and it’ll play you at them. (It’s even worked out some forced wins in classic games)
