More than 10, definitely. This Project Natal thing is amazing news for the gaming world.
I completely forgot about the other games being shown...! But I have to say Splinter Cell: Conviction amazed me as well.
Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...
