The Linux Gaming Cabal is a community group of linux gamers who band together to play native linux games in weekly events. Skill level doesn't matter, were just in it for a good time.
We usually play Sunday afternoons/nights around 3 PM EST (2000 GMT), but we usually have a few people gaming everyday.
We host all our own servers for the games. If you wanna play a quick game or just chill out join us in IRC at irc.freenode.net #lxgc
