It’s kind of wild but Fortnite makes (or made?) way more money than UE royalties, like magnitudes more. UE is a boon to the industry to be sure, but somehow 5% of games’ revenue simply isn’t the same as insane people spending money on stupid skins and dances.

Now is UE was used for 20 games as big as Fortnite, they’d be fine but most AAA companies won’t use UE if they expect a huge haul, with a few exceptions of course.
