I think he still lacks the total survivability and utilities of creative.
I kinda see the attraction too. Creative would be nice to build in, but hate the "left-click breaks everything" as it ruins all tools that are often much more efficient than anything creative offers(like equal exchange wands, 3x3 mining hammer/drills etc). So you would have to constantly change from creative to survival and back. And than you would need creative style flight solutions for survival and whatnot... In the end I just find it easier to build in survival all the time tbh.(and there is the survival game aspect attraction as well ofc).
Maybe what is needed is a "cheat menu" with options where you can choose which options you want to enable so you can customize your own difficulty setting. Like:
- invincibility
- hunger
- mob spawns
- left-click breaks everything
- creative flight
- spawn in items
- etc.
Then at the beginning of the game you can design your game mode exactly towards what you intend to do.
