On the surface, "Mass Effect 2" is the same basic game as its predecessor. You've got a space-based RPG cut from the typical BioWare cloth, though with more of a focus on action and real-time combat than most games of this type. The developer's trademarks are all there, however. You collect a large crew of followers as the story develops, each with his/her/its own backstory and related sidequests. The story unfolds via predetermined cutscenes and player-controlled dialogue trees. Your basic goal is to gather together an "Ocean's Eleven"-type team of experts, beings enlisted to provide aid in bringing the fight straight to the Reapers.
