I always do not understand why defold is never put into the fold [sic!] of those sentiments/discussions.
You can learn a clean & fun language (lua) and its JIT is maybe/probably running laps around something like GDScript, which in itself is proprietary and has no other uses for you than, ehh, Godot??
You can integrate C/C++ extensions natively, neatly exposing them through lua APIs.
Its mobile and web target footprint is unbeatably (?) small, desktop at least 10x smaller than Godot or Unity.
It is Open Source.
Maybe it's the "ancient" part, because more recent is always better ;)
