the fable series,condemned criminal origins,pgr series are very good racing games,halo series is such a great fps,left for dead series is very good.
kinect is so awesome and your gf will love it and play it so much, also i enjoy playing kinect so much i cant wait for the 2012 games even more to experience those what they have too bring to the table.
xbl and psn are close enough to not be that much of a factor, but if u or your gf like the idea of using a avatar and getting clothes and objects for them to show off and do the cross game chat with your friends when u play games. are worth the experience of the 360/kinect.
