Video game budgets are typically huge. It's not completely unusual for a big budget console or PC video game to cost over $200 million. That being said, the type of video games you'd expect to appear on Apple Arcade would most likely cost less. The indie-style video games you'd expect to see on Apple Arcade are usually made by much smaller development teams.

Apple has said Apple Arcade will come with games from Annapurna Interactive, Bossa Studios, Cartoon Network, Finji, Giant Squid, Klei Entertainment, Konami, Lego, Mistwalker, Sega, Snowman and Ustwo. That's an interesting and diverse list of studios and, at this point, we don't know precisely what all of those teams are working on.
