The Global Game Jam is a crazy event where a bunch of amateur (at least most of us are amateur) game developers get thrown in a room together for 48 hours with some computers and the seed of an idea.
I'm already tired just thinking about it. It starts tomorrow just after work and goes non stop until Sunday afternoon. Then again, no matter how tired I expect to be and how crazy the concept is, it's still going to be fun. I've had little game/story ideas bouncing around in my head for years now and it'd be nice for at least a part of one to see the light of day.
More news on this as the weekend progresses . . . Until then, some links:
