What was YOUR most influential game of the previous gen?

[TopCat8]

Of the choices provided, Call Of Duty influenced the industry the most, but personally, I was the most influenced by Super Mario Galaxy. That game it so great, I can't even describe all of it's greatness in words.

Though, of all the games released in the last generation, the one that influenced me the absolute most was Fallout 3. I love that game so much.
