Sony had its share of hits this past generation, but nothing that came close to the runaway success of the Insomniac-developed Marvel’s Spider-Man. As of late 2020, the open-world webslinging game had sold over 20 million copies, a number that’s undoubtedly increased since then, and Insomniac Games and the Marvel brand have arguably become the main pillar of PlayStation Studios’ output (Marvel’s Spider-Man 2 and Wolverine are slated for the future). Well, it could very well have gone another way.

According to an excerpt from The Ultimate History of Video Games Volume 2 by Steven L. Kent, in 2014 the newly-formed Marvel Games broke with longtime Spider-Man publishing partner Activision and approached both Xbox and PlayStation about making a new Spidey title, and possibly games based on other franchises. Xbox turned them down.
