My girlfriend and I played Mario for an hour, was fun to get her on a game for once. I admit the game is nowhere near as good looking as Rayman, but I hardly see any jaggies.
Scribblenauts has been awesome. I am nearing the end, so I am a little bummed, but it has been a blast.
Played one game of NBA 2K13 today and it was solid. No better or worse than the PS3 version, so it is refreshing to see developers doing so well with the system so early.
