I've written a few multi-player games compatible with this site's (planned) architecture. They will be listed here, and visitors are invited to participate against me and each other, and I'll apply my implementation of the Elo ranking system to whichever ones make sense.

• Dukes of Hell (original, done) might as well come over from 54E.
• Backgammon (mostly done)
• Chess (mostly done)
• Go (not begun)
• Diplomacy versions?
• A "hide & seek" game, whatever others in some old notebook of mine...
• (My generic game engine stuff would be nice... but that's 'way down the line!)
• (Unfortunately, I think card games will be too slow in this PBEM-y format.)

Possibly with mini-forums associated with each game. Plus maybe micro-forum per game instance: let players (and observers, if players OK) comment within game itself? Diplomacy-type games suggest a need for private messages... (adapt the "conversations" Vanilla application?)

Could also offer a high-scores gallery of any single-player games offered on the site, but if they're run purely in the client and report a score at the end, it would be ridiculously easy to cheat.

A fond memory from my old BBS days is the message forums dedicated to interactive never-ending stories. (Users take turns appending to the developing story.) I would like to provide a system that adds slightly more logic to the forum model, which allows users to contribute competing extensions to the tale from different points, and indicate which branches of the narrative they prefer. (Maybe separate votes per thread for "I like this entry" and "this entry makes a good ending.")

List the various storylines here, sorted by popularity or modification time. Don't let someone continue their own bit (and have a relatively small size limit per entry), and maybe some other anti-spamming stuff, without introducing downvotes.

MAYBE offer some general discussion forums (a category per major area of the site, I suppose: a philosophy forum etc), but probably only if/after there's a community clamoring for it. (Basically, add relatively normal Vanilla discussions views back into site.) AND/OR lean on user profile/activity pages (walls) and let users have Facebook-y interactions there. Could show the most recent such updates here (max 1/user).

In addition or instead, provide access/reference to any feedback (suggestions, bug reports, etc) section. And of course access to any per-game forums that may exist, as mentioned above. (Allow private messages? Maybe only between me and users, though?)

I think I am opposed to offering a users list (maybe unless we allow private messages between users), but here's where a link to such would go. (A partial such list would be whatever high scores/games rankings pages are offered.)
