The Marvel Cinematic Universe has come to dominate entertainment with its interconnected series of films and TV shows that all tie together to form a long-running, cohesive narrative. Marvel video games, however, do not exist in the same universe, telling stories entirely separate and unrelated to each other. Insomniacs Marvels Spider-Man games, for example, have nothing to do with Eidos-Montreals Marvel's Guardians of the Galaxy. Similarly, upcoming Marvel games such as Marvel 1943: Rise of Hydra, Marvel's Wolverine, and Marvels Blade, have no connective tissue.But there was once an idea at Disney to create a Marvel Gaming Universe that would do for Marvel video games what the MCU went on to do for Marvel movies and TV shows. So what happened?Speaking on The Fourth Curtain podcast, host Alexander Seropian and guest Alex Irvine recalled this MGU idea, which both worked on, and revealed why it fell by the wayside.Seropian, perhaps best known as one of the founders of Halo and Destiny developer Bungie, went on to run Disneys video game business before leaving in 2012. Irvine was the long-running writer of Marvel games, most recently working on the world-building, dialogue, and character backstories for smash hit Marvel Rivals.Discussing his prior work on Marvel games, Irvine discussed the scrapped MGU.When I first started working on Marvel games, there was this idea that they were going to create a Marvel gaming universe that was going to exist in the same way that the MCU did, Irvine said. It never really happened.Seropian then explained that the MGU was his initiative, but it never got funded by the higher-ups at Disney.When I was at Disney, that was my initiative, Hey, lets tie these games together. It was pre-MCU, Seropian said. But it didnt get funded.Irvine, who had worked on the iconic Halo alternate reality game (ARG) I Love Bees while at Bungie, went into some detail on how this MGU would have worked.That was so frustrating because we came up with all these great ideas about how to do it, he said.And I was coming out of ARGs at that point and thinking, Wouldnt it be cool if we had some ARG aspects? There would be a place where players could go that all the games touched, and we could move them back and forth from game to game. We could link in comics, we could loop in anything, we could do original stuff. And then, as Alex said, it didnt get funded. So we made a bunch of games.But why did the MGU fail to get the internal buy-in to move forward? Irvine suggested the idea became so complex it ended up putting some people at Disney off.Even back then, we were trying to figure out, If theres going to be this MGU, how is it different from the comics? How is it different from the movies? How are we going to decide if it stays consistent? And I think some of those questions got complex enough that there were people at Disney who didnt really want to deal with them, Irvine explained.Its fun to imagine what might have been had the MGU idea got the funding it needed to become a reality. Perhaps if it had, Insomniacs Spider-Man games would have existed in the same universe as Square Enixs ill-fated Marvel's Avengers and Marvel's Guardians of the Galaxy, with characters from each game making cameo appearances across the titles or the stories all building towards some epic Endgame-style event.Looking ahead, there are questions over Insomniac's Marvel's Wolverine game. Will it be set within the same universe as Marvel's Spider-Man? Could Spider-Man or any other character from those games end up making a cameo in Wolverine in some way?Alas, the MGU goes down as yet another scrapped video game idea.
