Out today is the badass NWN expansion Hordes of the Underdark. I'll be picking that up today.
Also, I just read some reviews for Call of Duty, which was released at the end of October. I don't know how this one slipped by me, but it looks really good. It's made by some of the Medal of Honor guys. I think those of us into FPS's should pick this up. I think I will probably get it this month (I'm buying 2 games today so I'll probably wait a couple of weeks). I played the crap out of Medal of Honor and it sounds like this will be a good successor.
One Must Fall: Battlegrounds looks interesting. An FPS/fighting hybrid. It comes out on 12-9, might be a game to keep your eye on. There's no reviews out yet, which is usually bad, but we'll see.
