Mass Effect was the story of a plucky commander uniting an oddball crew to save the galaxy. Sure, there was a seedy underbelly, and folks tended to do some pretty shifty stuff at the fringes of civilization. Part of the game involved confronting that from time to time, but we were led to expect a Gene Roddenberry happy ending for the most part.
That’s certainly not the case in the sequel. While the first game encouraged the player to navigate a fairly well-defined good/evil moral course, Mass Effect 2 forces us to wade through some fairly gray areas.
Spoilers ahead.
