SR4 should have been a DLC to SR3, it's really not a new game at all. Even $20 is too much for it imho, and I say this even though I absolutely love SR3.
Yeah, I was *this* close to pulling the trigger at $20, then I realized there's a ton of dlc that would total up to an additional $25, bringing the total up to $45 for the whole thing. Lame.
Think I'm going to wait till I can get the full package for under $20 for this one.
