Well, I'm not sure how that would go.
I'll be frank-I like Mass Effect better than SWTOR for one reason-Commander Shepard and the rest of the ME galaxy are incredibly in-depth, and your decisions effect that universe far more than SWTOR. After all, in Single Player you beat an area and never have to worry about fighting your way through new enemies.
On the other hand, Star Wars has its own merits. For instance, movies, flying games (X-Wing and Rogue Squadron original are awesome games), etc. You got to give credit where credit is due, after all.
But that's just my opinion on the overall thing.
