What I'd like to see in the future from this:
-Supply lines (IE, High food towns send food to low food towns), and maybe supply camps, which just gather food and send it away.
-A minimum of 1 male + 1 female to found a new town, so you're not left with 1 member until he dies, breaking roads when the town explodes.
-Towns taking up more space as they expand
-Migration to more popular/successful towns from smaller ones
-Faster travel once a town reaches a certain size
-Agriculture (areas that produce more food when worked on by people, made by people)
-Animals/other resources
-An easier tool for making new land (like, raise elevation, lower elevation, etc.
-Better looking bridges (say, made out of stone, versus sand)
-Volcanoes, and other disasters (tsunamis, hurricanes) and weather.
There is a ton of room for expansion, but what's here is really cool. I really hope you continue this project.
