Not sure if you want most influentail or best

Anyway most influential would be

Gears of War
Wii Sports
Call of Duty 4
Just Dance

Best games would be

Halo 3
Bioshock
Dark Souls
Elder Scrolls IV: Oblivion(with a few mods)

Don't forget Uncharted. Most games in this coming gen will be taking from its immersion, cinematics, gamplay and camera movement.
