The historical accuracy of medieval city-builder video games
I would love a building game where you can't build roads. All of those building games so far allowed that, but I think it would be more fun to just allow for constructing building, and roads/pathway would form depending on their connectivity inside the production chain. I.e. you wouldn't connect your farm to a butcher, but pathways would form and eventually turn into street based on the amount people from dependent shops walking to it (also depending on terrain and usage of i.e. horse carriages).
