At least Unity should remove retroactive effect from their new pricing terms. Then negotiation with users would start.

Because mech has rigid body and gamedev likes controlling rigid body

I'm now interested in UPBGE, a fork from Blender with game engine. It seems useful for learning modeling and gamedev.

I think the reason beginners want to use Unity is because that is what they will need as professional game developers. But if professional game developers stop using Unity, then there is no reason to use Unity, no matter how beginner-friendly pricing it is.

Thankful to communities, building dev env on Linux is easier than that on Windows.
