What Games Do You Play On Your Media Center?

Soo? As the title hints at.. What games do you play? 

I remember grinding out many of a level on WOW early on in my addiction. Of course, as my addiction grew, the relaxed nature of playing just wasn't cutting. I played a few other games but never really got into the gaming end of things after that. I suppose it has to do with having the right peripherals to play with. I would imagine the Need For Speed series or a quality flight sim would be a whole lot of fun playing on a 60"1080p TV.

I'll add to my previous question, is it easy to launch them and have the proper resolution settings?
