> PS: a standalone "bring your own engine" hackable Unity editor would be great, but I guess that doesn't quit fit into Unity's business model

I’ve been thinking about this a lot as I want to write more standalone games with minimalist runtimes but also don’t want to give up the QoL you get with a decent scene editor with runtime inspection and “fiddling”.

One thing that intrigues me is the recent rash of tools made with Godot as it has a pretty good UI system that is used to make their own editor: https://itch.io/c/651672/tools-made-with-godot-engine

I could see a decent open-source game editor made this way as well. But don’t have the energy to actually do it myself.
