I feel sick for even admitting that I play MineCraft, but yeah ..I do, unfortunately.
I play lots and lots of TF2 and I sometimes come on XBL - I hate MW3 and all that though, I just play alot of Gears of War.
Spartan: I'm pretty interested in Ace of Spades, I've heard it's some mixture between Minecraft and TF2 ..might try it out sometime.
