You gotta love Katamari Damacy, We Love Katamari, Guitar Hero, Mad Maestro, Incredible Crisis, DDR, beatmania, Karaoke Revolution, God of War, Final Fantasy X-XII, Space Channel 5 Special Edition, Taiko Drum Master, Frequency, Amplitude, Metal Gear Solid 2-3, and all that stuff.
It's Xbox that's lacking the games (assuming you own a PC).
