Well City of Heroes is still my MMO of choise that eats my life away, although currently having a break from it.
I finally got around to buying Fallout 3 and Dawn of War 2
greatly enjoying Fallout3 when it's not BSODing on me, which is becomeing more and more frequent.
So untill I find a fix for that I'm currently installing dow2 (god this has been a painful process)
Also dug out Hellgate London and played some more of that, you may not be able to play online but it's still good offline, like a post appolictic 3d diablo.
