Godot can use C# like unity does and it’s FOSS.

Unreal uses C++, so you have to learn a different language if you’re coming from Unity. And they also take part of the profits you make. Unreal has its advantages obviously, it’s an amazing engine with amazing graphics, but if you’re used to writing code in C# and don’t want to learn something completely different, Godot is a very nice alternative

Godot is FOSS

sure, switch to unreal engine, then when they pull some equally dumb move you get to do this all over again!
