Street fighter looks OK, Ridge Racer looks pretty crap to me :-\
Played on some a few weeks back at a pre-launch event.
Street Fighter did look ace, as did Zelda. Ridge Racer wasn't great, nor was Asphalt. Res Evil looked decent, Kid Icarus was ok, but the best use of the 3D I saw was on LEGO Star Wars 3 and the Rabbids game.
Overall though I was extremely impressed by the console and most of the games
