Bad Company 2 multiplayer is wicked fun UT. So is Left 4 Dead when you get a group of friends together on the same server. An unappreciated game I'm into right now is World In Conflict. It is a late 1980s based Cold War real time strategy game similar to Command and Conquer. Except WiC features an awesome soundtrack including Tears for Fears. Portal also is really, really good.

Anyone got hands on Assassin's Creed 2 yet?
