How did Unreal manage to evolve so quickly? If it was just one patch notes then may be just a coincidence, but they have manage to do it every time for the past months or years. I cant think of a single software / middleware that has this pace of development. And Games Development were suppose to be hard?
They also a have ton of licensees which are AAA game studios with qualified profesionals often backporting fixes and features into the main branch. Appart from that the engine is completely open sourced.
I also get the impression Tim Sweeney, the one man developer behind the first engine, is rather good at assembling and managing tech teams.
I guess its a really clean architecture- developed together with performance-senstive personal. The good architecture allows for fast movement, the performance sentive check ups, keep it from beeing slowed down from bad architecture decisions.
It probably helps that they are among the most if not the most popular third-party gaming engine on PC, as well as the de-facto cross-platform (PC and consoles) gaming engine.
Well, entertainingly enough, DRM is serious problem for farmers these days. (Much worse, tbqh, than it is for techies.) Even farmers run unapproved firmware these days.
