At the same time I would note that I don't inherently have issues with comic books and such in the game world but why would there be spider man comics? Why would there be Captain America comics? Why would there be superman?

There should be Icon comics, Lady Liberty comics, ect. Hell I've referenced and so have a few others more self contained universe stuff, like the in universe movie about the Good Doctor and Lady Liberty and the other WW 2 era supers, which was specifically noted to be the latest in a long line of that sort of thing.
