I just got started with a Unity project a few weeks back. My only goal right now is to build out a concept to see if it even makes sense to invest real time into. If I get to the actual money piles and it turns out the terms of doing business with Unity are too intolerable, I would consider swapping paths.
There are a lot of developers who seem interested in the idea of making games, but they get so caught up in the intense tribalism around the various approaches that nothing meaningful comes of their efforts.
I recall discussions around how quickly projects were able to be migrated to Godot. So, what's the harm in beginning somewhere else?
