I've been playing NFS Shift with my Logitech G25 lately. And, today I just got back into playing Thief Deadly Shadows. I also play Multi Theft Auto: San Andreas (MTA 1.0.1; GTA: SA multiplayer mod). I have a lot more games as well, but I'm only going to load on the ones I want to use the most. I also play some D&D Online (MMO) occasionally. Last night, I played my first multiplayer Checkers from the Games window and I won, woo.
I can't wait for Diablo 3 to be released. That game looks awesome, having owned and played D1 and D2. Also, I'm looking forward to Bioshock 2 as well. I might even load back on Bioshock 1 again because it too is pretty fun.
