Unironically this is the one area where Epic Games is absolutely in the right. They have a 12% royalty on games sold on their platform and a 5% royalty on sales over $1 million for games made with Unreal Engine, with the UE royalty being waived entirely if it’s sold on the Epic Games store. They get a reasonable cut for maintaining one of the most powerful game engines and charge nearly a third of what Valve does for their storefront. If the Epic Store wasn’t so dog shit, they’d be an actual competitor to Valve
