3. Mass Effect (360)

Whether they knew it or not, the Xbox 360 scored one of the best platform-exclusive franchises of the decade when they got BioWare to create Mass Effect for the Xbox 360. While sometimes the main characters appear to need the best eye cream for dark circles, the truth of the matter is that the game was one of the genre-defining titles of the 360/PS3 era.

The space-opera role-playing shooter owes a lot to both Star Trek and Star Wars while somehow being its own thing as well; and although the second title in the series didn’t arrive until the decade was over, the first title was promising enough to show that the series, planned as a trilogy, would be rock-solid.

No matter what type of “Shepherd” you created, he made a memorable hero and the universe of planets he was given to explore was quite impressive. It’s one of the few that have made me want to play to completion; not just once, but more than once.
