Afterwards you can free roam. Do the challenges that are all around the cities (like in Spider-Man 2). You can collect the comics that are in the game. Or you can play the story mode of the game all over again but with all the moves and combos you already bought, so you won't start from scratch. I played about 3 hours everyday since I got it. Some of the missions are pretty hard. I would fail the missions sometimes because I wouldn't complete my objectives.
I usually play an 1hour and a half at most at night.
