Godot is not a Unity replacement.
I think for the last few years there's been a really nice three tier ecosystem for engines: Godot for small projects with rapid development like gamejams and home devs, Unreal for big serious projects that require performance including Triple A, and Unity in the middle straddling both spaces and the gap in between.
Now, if Unity DOES collapse as it seems intent on doing whether it's from this fumble or another, that knocks out that middle option. So now the reality is that devs need to make a much harder call about whether their game is small scale or large scale, without a goldilocks option in the middle to choose.
@ash Unity, it seems to me, occupies some solid usage in what I tend to think of as "prestige indies".
Alas, that's the group that *really* can't afford to be retooling all of a sudden. Changing horses midstream is so damned expensive.
