Hi
I've actually never been working on games but I've used Unreal Engine for concert visualisation live VFX. Honestly, I've never heard about Godot but it seams like a very cool alternative. I figured it depends on which program you like more since Unreal Engine is an already optimized program for Game-Development.
Im gonna look into Godot it looks nice. Btw, what kind of Games are you developing? Sounds cool!
