If any of you are feeling nostalgic today, or just want to play a good game, or both, Doom has made it's way back onto Xbox Live. 

We really don't have to go on about how Doom was revolutionary or a good game and all that. By this point, most anybody over 13 who's ever played a video game knows what it is. But you must be 18 to play it, says the ESRB.

Doom runs you 400 MSP on XBLA, and it's on sale right now.

I'll be picking it up finally, having never played it on a console. Anybody else ready to take a painful, chainsaw-laden trip down memory lane?
