It's all starting to come together now, the Mass Effect trilogy is, in fact, a prequel to WH40K. The big war ends in a draw, the Reapers retreat to a neighboring galaxy, mr. Man becomes the God-Emperor and all the planets are ugly hellholes.
I didn't like the story or the extremely formulaic mission structure in ME2, but the writing was good, the combat decent and it provided some more awesome Shepard moments.
