Most people didn't pay attention to Miles' game, as even Sony outright called it an expansion pack, and it was rightfully assumed to be irrelevant spinoff fluff.

Which means that 2 is coasting entirely on 1's successes. Vanilla original 1 specifically, as I saw a lot of people surprised and upset at the Tom Holland model they replaced the original Peter with in the re-release of it. So this one had hype from people who paid zero attention to the greater picture, and just remember really enjoying the first one and went from there.

I doubt 3 will flop, but I think it'll be a notable downtrend overall.
