As several others pointed out, Marvel themselves are helping to market this game. Their E3 video for it on their YouTube has 25 million views, and I guarantee they’ll be pushing it as hard as Sony. That said, I’m gonna have to say Spider Man will sell more copies and push more hardware, especially if Sony does a badass Spider Man-themed PS4 that is bundled with the game. Both will be huge critical hits and top sellers, no doubt.
