@EtheralGamer Heh, Rachel. We always iterate our engine between games. We don't have more than one though.— Insomniac Games (@insomniacgames) June 27, 2016
@vampirepietro yes we have a huge team working on this game full time— Insomniac Games (@insomniacgames) June 27, 2016
Marvel is allowing Insomniac to tell its own story with the game, in return for it being a quality experience, which is something we're sure Insomniac will manage.
Some have brought up the fact that there are some changes to the Spider-man costume in the trailer, and not everyone likes that fact, however we're told that every change to the costume has a meaning behind it, so we'll just need to wait and find out what.
