Pros: Allows me to throw people out windows and romance Yvonne Strahovski ... in the same game!
Cons: Planet scanning is not nearly as fun as window murder
Mass Effect is great. Mass Effect 2 is better. Bioware polishes their RPG/action formula to damn near perfection in the second chapter of this space saga. Decisions you made in the first game carry over into the sequel, making the universe feel like a place where your actions have serious consequences. One of the best game experiences of this generation.
