O3DE

I'm keeping my eyes on O3DE as Godot's designs aren't conducive to high performance operations, or lots of actors (at least, I haven't had a need for a lot of actors, but I do find myself needing to use Observers). But in terms of trivial design, Godot is much closer to Unity, and in a lot of ways, its Node system gives it an edge for extendibility and ease of use.

I'm seeing Godot mentioned a lot: one major distinction between O3DE and Godot is that O3DE is "ECS-based" while Godot is "OOP-based" [1][2]. This makes little difference for the hobbyist gamedev, but it has ramifications for large projects with many interacting systems. Proper ECS architecture better supports the latter case [3].
