It is impossible to balance anything around everyone in a game like Minecraft. Everyone experiences the game differently. Like, when I build a TE3, or RotaryCraft, or Gregtech or any type of little factory I like to automate the factory and imagine that automation is a bunch of people working in the factory. I mean I recreated a vanilla village in my AgSkies world! It is crazy silly to pretend imaginary people are wondering my bases. I know, lol. But to me that is one of my favorite things I get from playing this game.
I seriously doubt many others think that when building something.
Everyone has their own experience. Many are perfectly happy just throwing down a bunch of cobble, placing a bunch of machines on it and their biggest desire is to get some amazing system built that can do wild stuff. That is awesome, but totally not for me.
Like all that cobble in Dire/Pahi's AgSkies would make me want to jump over the side into the void. Everyone has their own desired experiences and as long as everyone is enjoying themselves equally all the experiences are equally awesome and equally valid!
Just look how these two pictures of the exact same mod pack show how differently people can experience the same game.
Edit:
(also just realized that being a YouTuber who spends hours talking to myself recording videos, which my family & friends think is weird lol, might help explain why I imagine people wondering around my base. )
