It's a cliché answer sure, but GTA 5. I was genuinely shocked as I'm sure so many where when it smashed through all previous titles to take the uncontested #1 position. I'd even go so far as to say I won't be shocked if more "open world sandbox games with heavy third person shooting and driving elements" replace the current trend of "modern military FPS with strong focus on online multiplayer" as the go to copy-cat model.
