Yeah but they are all stuck in some sort of development hell. Like UT is barely making significant progress and Fortnite has been a mess. I guess Paragon worked out ok? Not sure about that, though. edit: Seems to be in Early Access still.Epic atm is a provider of an engine as a service with games that they use as advertisement for devs to show what UE4 can do.
And yeah, they are still a super succesful company and I'm sure selling Gears must have brought in a lot, too.
