The Ghost of RubangB on 11 August 2008
Portal, Galaxy, Rock Band, and Wii Fit should be way ahead of it, possibly tied for first.
EDIT: Nevermind, Rock Band is a distant 4th. I forgot it was in Japanese arcades forever and the only innovation of Rock Band was bringing it stateside.
Halo 3 is a distant 5th.
GTA4 is a distant 6th.
These people on crack.
