So, I finally kicked the Oblivion habit long enough to install Resident Evil 4. As a first-time player, I must say it's the best of the series. 2 remains my personal favorite, though.
I should probably install ArmA: Combat Operations next, but that Oblivion itch is still there, in the back of my mind, and I've also been thinking about trying out Neverwinter Nights again.
My first time through NWN, I got through the first chapter and just quit out of boredom. It plays identically to KOTOR, except without all the rad Star Wars stuff.
I should get back to playing Gothic 3 again someday, as well. When I first got it I absolutely loved it, I played it for 50 hours, and quit out of exhaustion. It was just too epic for me.
