I'd say:
Wii Sports-kind of defined the wii revolution with its simple, addictive gameplay that anyone could enjoy.
Gears of War-for better or worse, put cover based shooting on the map and it blew up from there.
Uncharted 2-took cinematic, story driven gaming to the next level, the first may have gotten the ball rolling, but 2 took it to another level entirely.
Skyrim-Bethesda dumbed down the elder scroll formula enough to introduce even more people to the rpg genre.
Batman Arkham Asylum-great gameplay, inspired a trove of knockoffs like god of war did the generation before.
