I've been cutting back my WoW play to just raiding, which has left me more time to finally work on the game backlog. I've got at least a dozen that I've started and then quit in the middle, and a lot more than that I haven't even opened yet.
I finally finished the first and second playthrough of Borderlands on my siren. I also did both playthroughs of the Zombie Island DLC, which was a lot of fun. I'm slowly working my way through the new one now.
After lurking in the Modern Warfare 2 thread a bit, I decided to finally get around to finishing Call of Duty 4. I had about three missions to go in the campaign from where I left off before. I'm now working my way through Call of Duty 5, which has been a blast, so far. As soon as I'm done with that, I'll finally get to Moder Warfare 2. I'll probably wait until then to finally get into the multiplayer, as well.
