I recognize you perfectly right fastlane69

For my part, if i'll never make a game, why not , perhaps better than begin and never finish ??

Don't want to may more for 3DGS , A7 that is not as complete NExt Gen as Unity Engine
Unity to have all features need to pay very big and Editors for PC version not here at the moment , buyt it's the engine i like ,
and very easy language and engine code to use, lot of formats supported :
like Blender with animations directly,
more than 40 shaders, water,glow ,refraction,normal maps ,full screen effects ...

But you have said the right points fastlane69 even in the end when comparing with cars
But perhaps you forgot some points :

-The Ferrari will attract all people eyes and the old civic , not a lot will look at.
(i mean next gen graphics)

And tunning your old Civic , even more fast etc ... won't reach how
comfortably/easy/fast you can go with Ferrari
( i mean editor/workflow/engine).

The joy is not the same using a ready engine ,and another lacking today things/workflow.
(when lightmaps mixed with shaders ,lights , and shadows automatically?)

Well i stop , like you said, i should do some models instead of typing it should be less time wasting
