You might be able to do something akin to early simcity or simtower where you decide on the zoning (what's allowed to be built where) while your simulation decides if it's successful or not. Your NPC's may want to start a new business but there's no commercial spots available, or lease office space etc. They move out if they close down or decide to move to a better place. The player's job is to monitor citizen's happiness/goals and plan the town accordingly.
