Commander Shepard thought the day was saved when Saren and his ship of doom, Sovereign, met their Maker. But, he/she (depending on how you chose to customize your character) returned in yet another intergalactic dogfight, this time with the whole collective species of Reapers, in Mass Effect 2, with a narrative driven by the mysterious Illusive Man. The game was heralded as one of the best of 2010 (we actually named it the best), with refined role-playing elements intertwined with awesome biotic powers and murderous third-person mayhem. If there's one thing mama taught us to appreciate, it's murderous mayhem. Thanks, ma!
