Left 4 Dead 2 (Xbox 360)

Quick Thoughts:

1. Really great online experience.
2. However, the 'in-room' play makes the game.  The cooperate style and the split screen are excellent.
3. I actually think I liked the first one better (Probably because it's a little easier).
4. As first-person shooters go, this is outstanding stuff.  Killing zombies is a great time.
5. Not much in the way of a story-line.  Also, the game play is fairly linear unless you're doing the multi-player.
6. The new weapons are a nice touch.  I was especially fond of the chainsaw.

Metacritic Score: 89

Bioshock (Xbox 360)

Quick Thoughts:

1. Great first person shooter
2. Excellent Graphics
3. Fantastic Storyline
4. It's and older game by now.  If you haven't played it, you can pick it for cheap on Ebay.

Metacritic Score: 96
