My biggest concern with Spider-Man is that it's potentially going to feel like a big DLC instead of a proper sequel. That Miles is in it is probably a positive since it's a bit different. I knew of him from waaayy back, but the Spider-Man game on PS4 was my first exposure to him.
This is my exact opinion on the game. It just seems like an expansion pack, going off the title. Oh well, only time will tell when more about the game is revealed.
