Mass Effect 2 once again thrust players into the shoes of Commander Shepard as he (or she) saves the entire universe from the threat of the Reapers.

Few games make you feel as if you're the protagonist of the game like Mass Effect 2, with the ability to customize your character and pursue romances with your crew. Though some would argue ME2 is more of shooter, it retains enough RPG elements to make it one of the best in its class.
