Godot Community

I didnt switch from Unit from Godot, I started directly with Godot a few months a go, the reasons I despise Unit are 2 :

1. Dot.net dependence and not integrated code editor ( because of this dot.net ) : for me its a very very big limitation, and this is the one reason why I dont use c# in godot also.
2. UnitHub BS : I tried a few times to use Unit, but I was unable to make it works in linux with out unithub, and unithub is a big no for me.
   Adding to that, I tried Unreal as well, it works very very well, I had no problems setting it up, compiling etc, very good performance, but I guess I still prefere coding...

Unfurtunally godot dont have a good physic system for cars...
There is a guy that is building a new one using gdscript : https://www.youtube.com/watch?v=6hEL66P1WQw
In general, if you need very realistic physics, you will need to build something similar, and its quite complicated.
