Uncharted 2: Among Thieves
You don’t need me to tell you how good this game is; the rest of the gaming world got there first. I don’t know if any one game can be a “system‐seller” — but if you already own a PS3, it’s inexcusable not to own Uncharted 2.
It’s not just good; it’s unusually, surprisingly good. It’s unusual for a game to be this much better than its prequel. It’s unusual for a game to make such large graphical leaps over its prequel on same‐generation hardware.
