But it’s not a monopoly, it’s one of many, many devices. There are, at time of writing, many games platforms and many application platforms: XBox, PlayStation, Nintendo, IOS, Android, Windows, MacOS, Linux, with Google Stadia too.
Developers make a choice and everything sold on those platforms has distribution costs. Fortnite is available on most if not all of those platforms. AND, players play against one another through the internet not through a private developers network. So there’s plenty of competition. Why Epic aren’t demanding Nintendo and Sony take a lower cut is a mystery. Or maybe not?
Epic have massively, massively, overplayed their hand here. Instead of creating an amazing new game and using THAT as leverage to platform owners for a deal, they’ve made a satirical video, broken a contract, had their bluff called, and cemented their place in future business school classes as how not to go about a negotiation.
