Yeah I was a game programmer in the early 2000s. Unreal made my jaw drop back then already. They've always been state of the art (although arguably CryEngine had the lead for a while), long before Unity came around. As you might remember, it started out in 1998 as the game Unreal (and then Unreal Tournament) which was a kickass first-person shooter. It has been around for 25 years now.

Unreal is now also selling their engine to Hollywood productions that want to replace green screen with real-time effects for the actors to play against. It's impressive stuff, and I bet they're going rake in tons of money through that channel as well. Unity is just not in the same ballpark.

That said, there's room for Unity if they're willing to find a business model where they don't compete head-on with Unreal. As the article indicates there is (was) a strong community providing tons of cheap or free-of-charge assets, and it's been very appreciated among indie devs for these reasons. Unity excels in support for mobile and web platforms. They don't need to make their engine support all the latest cool technology. They just need good developer relations and tools that make it easy to turn cool ideas into fun games. The fact that they squandered their biggest asset (the community) shows that the leadership does not comprehend Unity's value proposition. It is being lead by fucking morons.
