As mentioned, it depends what the limited edition actually is. Mass Effect 2 came with fancy weapons and armour that were much better than the stuff you start with... I really don't like this, or see the point in it. I want to play games that are a challenge, not spend even more money to unlock an easy mode. I've never really been one for soundtracks, I don't think a game's ever really gripped me enough to want to buy one, though I've downloaded a couple, there's some fantastic orchestral Phoenix Wright tracks that people have released.
