Because it’s boring. Has no goal. Has an ugly art style. And is to limiting to actually be creative in.
See, this I have a different opinion on.
Let me show you something.
I built this. All of this.
At this time, it remains incomplete. The intent is to bring it over to my family survival server when it's done, so there's a great deal of renewable materials in the palette. Quirks of spawn mechanics have been thoroughly abused to keep the lighting down. There's been selections throughout to add depth and texture.
The ceiling is particularly bland, other than its shape. I still have some additional furniture to work on. There's people who would give me hell for all the brown I used. More yet to be done.
Nevertheless it remains a creative expression. A lot of agonizing hours over design choices of various stripes, all compacted into a relatively minor space. Where you see limits, I see possibilities. And I seized them to the best of my limited ability.
To say that somehow none of this is possible effectively denounces the work I've done.
It is with this in mind, and a heavy heart, I have to say I can neither agree with nor support your stance in any way.
I hope you understand.
