This looks like an interesting set! What genre does each game fit into? Grand Theft Auto and Kinect Adventures are a given, but what about the rest of them?
Street 2 is a street football game for Xbox and rated E. Blinx is a cartoon violence game but is rated E. pretty fun though. Blood wake is a naval combat game rates T, and kabuki warriors is a fighting game like mortal combat but with less blood and is rated M because of little blood and fighting! (All but gta IV and kinect adventures are for Xbox)
