We've seen a trend in recent years of developers dropping their own game engines to move to Unreal Engine 5 as their game development software of choice. CD Projekt Red and 343 Industries were a couple of the most notable examples.
It's easy to see the appeal given UE5's graphics capabilities and its wide use, which saves new recruits from having to learn a proprietary engine. But Unreal Engine 5 has its detractors, particularly due to performance issues on lower-end hardware.
