But for my projects I think I'll keep using Godot. I really want to make a game, and not the tooling required to make a game. That said, I've dabbled in GDExtension, and if I really need to have something performant, I'll use that.
I've got huge amounts of respect for people doing it this way though. They have a level of control over their work that a Unity or even Godot developer cannot hope to have. It has, like any game dev approach, it's pros and cons
