You there! Have you ever played Munchkin? It's a multiplayer card game about dungeoneering, created by
Fighting Fantasy co-creator the other Steve Jackson. It's enormously entertaining, primarily because it's designed almost entirely around screwing people over. It's shallow as all hell and has arguably been flogged into semi-embarrasing status by the endless slew of expansions and modifications, but it's also a great night in. Or even out, if you live near a pub that isn't full of large, angry skinheads who like to punch boardgame players in the face.
There isn't a videgame version, and I'm not entirely convinced there should be (this is, after all, a game about getting really, really cross with the people you're sat next to) - but there is now a 'rigged demo' intended to explain the cartwheeling, sadistic rules of play.
An older version has been around for a while, via the complicated magics of downloadable and printable PDFs, but it's now all spanglied up, 100% online and in-browser thanks to Flash. Thanks, Flash. Thlash.
It doles out the rules remarkably well and with an entertaingly sardonic tone, I'd say. Go see.
