Since I don't play a lot of games online, I don't meet a lot of Xbox Live folks. I'd like to change that. Below are some of the games I'm most into. Please add me if you have any similar tastes in games!
Kinect Fitness/Rhythm: Zumba Fitness Core, Dance Central 3, Dance Central 2 (trying to get a few more achievements!), Your Shape Fitness Evolved 2012, Nike Kinect Training, and Junk Fu. I don't have Fruit Ninja Kinect yet, but I'll check out the trial sometime.
Xbox Live Arcade: Peggle, Trials HD, Roogoo, Braid, Doritos Crash Course, Carcassone, Crazy Taxi, Ilomilo, Uno, Geometry Wars Evolved 2
Some other Xbox 360 favorites: Sega Superstars Tennis, Civilization Revolution, Split/Second, Portal 2, Catherine
