The game bears the catchy name "botsbotsbots", and features- you'd never guess: robots. It's a two-player-game that looks superficially like chess, only, it's chess with laserguns, flamethrowers and heavy artillery, and it plays a lot faster (most games last no longer then 3 or 4 turns).
Downsides are that it does not seem to be 100% bug free yet and that it generates a lot of mail (one "new turn" message per turn). But I still warmly recommend it
Anyway, here's the linkie!
