-more customizable town planning. You can sanction sections of land in town for commercial (stores) and residential.
-in order for your town to prosper you must have means to acquire food and water. digging a well or having the village by a body of fresh water solves the water problem. sanctioning some land for agriculture and ranching could solve the food problem.
-trade will play a big part. If your city doesn't have enough food, but has an excess of lumber, then you can make an import/export deal with nearby towns or cities that might need lumber, but have an excess of food). When the town becomes big enough, merchants will like to set up shop. They can either buy land and make a building, buy or rent an existing building, or buy a license to set up shop in the streets
-things like taxes or stimulus payments may have major realistic effects on you towns economy
- obviously you must hire guards to keep the peace.
- certain illegal organizations may attempt to make deals with you for considerable profit at the expense of safety.
- organized crime syndicates may ask you to pay "insurance". of course if you refuse, there will be consequenses.
- the town should eventually be able to get city walls to keep unwanted visitors out.
any more ideas or any thoughts on some of the ones i listed?
