Funny, I chose UPBGE for 4 reasons, non of which effect depsgraph much:

1. EEVEE
2. I know how to use Blender
3. The GPL License ( because I want my game to be GPL’d too )
4. I know how to use Python

So I never felt like I’m missing out on Geonodes or whatever. And depsgraph was only an interesting challenge to tackle.
