Forgot to mention that I play NBA 2k6 on my friend's XBox just about every time I go over to his place. We mostly just do dynasty mode and simulate all the games for about 10 years. We just do the general manager stuff and try to make horrible teams into contenders. It's very addicting.
MVP Baseball 2005, I'm only just now getting decent at it after having had it for over a year
X-COM, occasionally, but it's screwed with me so we're not on speaking terms anymore
The Chaos Engine on an SNES emulator, absolutely awesome game
Sold my Xbox a little while back and haven't bought the 360 yet, so I'm a man with no games... Not sure when I'll get around to buying the 360, but it'll have to be soon. Definately before the '07 basketball games come out.
