Lack of content, lack of story cohesion, lack of rogue's gallery (most are dead now), lack of miles' agency for a majority of the story and worst of all lack of polish
insomniac. Spider-Man 2 is severely lacking in comparison to both of the other Spider-Man games, and it stings more this time as you can tell that crunch fucked this game, and it shows more than ever maybe. DLC might be able to fix the lack of content it, but man, for the amount of money they want. Get the other ones at time of writing, they're on sale on steam.
I can only hope insomniac actually takes feedback into account because this is a severe step-down from the first 2 games.
