That's why I was quoting minecraft. If you have already played minecraft with villagers, if you don't have too much, it's okay. But if you forgot to stop your auto-breeder, it's just Lag-Land (see unplayable). And yet minecraft is a pretty basic game with NPCs doing basic stuffYeah, that's true. That would cause a lot of CPU problems
I wish all cyberpunk NPCs had routines, dialogs, and make their living (make it really realistic), but right now it's just a dream.
