The wildest video game budgets can't hold a candle to GTA 6

A billion-dollar video game budget may seem surprising at first glance, but it starts to make sense once you consider that a modern game often has just as many moving pieces as a Hollywood production. You need actors, writers, programmers, animators, designers and composers among others to make an expansive open-world game. And short of a few outliers like the Avatar series, movies are typically in active production for a couple of years. GTA VI has been in active development for closer to a decade. Once a game is nearing completion, it usually goes through a rigorous testing process that requires yet another team.
