I just got Anno 1880 and it's latched right on to the optimization part of my brain.
If I just arrange the pig pens this way for soap production I get this modular section I can paste and rotate, plus it saves 4 tiles on my island
It has not been good for my sleep.
It's not as bad as Factorio though, that game turns me into a husk of a human that wants nothing but to make the factory grow.
