For the record: Unreal five may be neat, but I personally welcome the death of the unreal dominance and the rediversification of games and gaming engines; when every game comes out relying on the same engine underneath, they intrinsically develop a sort of saminess that, in the most recent generation of games was getting stifling - I'm sick of seeing games piggybacking on the unreal engine rather than developing their own, and the various games I've seen recently that have shifted to develop their own engines for their own games have been a breath of fresh air by comparison.
Sounds nice but look at Biowares Frostbite disaster. The engine was crap for RPGs. Or Red Projects Cyberpunk 2077 disaster with the Red Engine. Developing their own engine is AAA Tech and Unreal has in the moment a technogical advantage and ALL users can profit from it.
