Well, I'm mostly playing the following during my spare time:
Football Manager 2006, a football (soccer) sim game that sucks my life away hours at a time. And OMG, '07 looks so much better!
I'll never get anything done.
TES IV: Oblivion, still play it some...but I dunno, after awhile the 'dungeon, ruin, fort, city, fort, ruin, dungeon, etc. etc.' gets boring after awhile. The world just doesn't hold my attention in the way that Morrowind, one of my most played games ever, did. I want so much to love it, and I'm so close, but I just can't.
Been thinking of trying OOO 1.3 and some other mods and giving it another go...dunno, we'll see.
Civilisation IV, JUST ONE MORE TURN!!! Damn Sid Meier.
