There's a difference between caring about the small things and caring about things that don't matter at all. Look at city skylines 2. Every tooth in every person is individually rendered. Why? Every house hold budget is tracked and managed. Even though you can't do much about it.

Lots of technically advanced simulations are going on in that game to build the most advanced simulation. But people don't play a game became its simulating a city accurately right down to individual teeth in every citizen. They play a game because it's fun.
