I've resisted moving to Godot because I already know Unity so well, but I guess they've finally forced me to switch.
It's optional (Godot is free), but if any developers who are considering switching from Unity want to see Godot development accelerated, consider kicking the project a few dollars a month: https://godotengine.org/article/godot-developer-fund/
From Wikipedia:
> “…it represents the never-ending wish of adding new features in the engine, which would get it closer to an exhaustive product, but never will.”
I think Unity is doing this to toe-to-toe with unreal, both "big boy" engines.
