Current AAA games can take at least a decade in development if no longer. For example, if a studio started working on a big project right now, it would have to be for the PlayStation 6 and the next Xbox.

"Other Triple-A games take even longer to develop. For instance, according to one Microsoft executive, [REDACTED], a forthcoming title from the [REDACTED] franchise, may take a decade to develop. Microsoft should go all-in on video game development and leverage its smorgasbord of first-party studios.
