This month is pretty busy if you bounce between console and PC. Assassin's Creed 2 just released, as well as the New Super Mario Brothers Wii, which after watching Misty play quite a bit looks pretty fun. I haven't played enough of AC2 to have a verdict yet, most my time has been occupied with L4D2, which has a lot going on for me. It's similar to the first but also very different in a lot of ways. I also did get the chance to play some campaign of MW2, which was simply amazing.
In terms of what's coming up, God of War III, Final Fantasy XIII, StarCraft 2 (supposedly, I haven't kept up on all the details about the release date), new C&C, Splinter Cell Conviction, BioShock 2, Mass Effect 2 all have 2010 release dates. My console side tends to show more with release dates. Also, new details on Guild Wars 2 were just released not too long ago as well.
