It's a good point to make, most people don't care about the rules set, and won't really notice it unless it's actively bad, sales are mostly about what people perceive the story and the companions to be like.
@fylimar I played The Old Republic MMO like a single-player game too (in fact it's the only MMO I've ever played), they really had some great storylines and good companions, it's too bad we probably won't be seeing anymore Knights of the Old Republic games in the future.
