Does anyone here game in Linux at all? If so, what games do you run, native or emulated (Wine/Crossover), and where do you foresee the future of gaming on Linux?

Lately, I've been using Wine to play a handful of games. Right now I'm getting Skyrim onto this machine through Crossover. I think the future of gaming on Linux is going to start looking good, with Gabe Newell talking about Linux being the future of gaming and the soon to be unveiled "Steam Box", which has been rumored to run some variant of Linux (Probably Ubuntu)
