Bridges would be a great option, and honestly more rivers in general would be neat. (Fishing/trading boats even??)
Having random events occur sorta like frostpunk or stellaris- stuff that happens in your town where you have to make a decision, similar to deciding how the bandit attacking happens. A message pops up asking you to decide how to handle it. Could be anything a medieval mayor may have to deal with.
Events or quests to do as you explore. As is there’s a very big map to explore and not much in it.
The game is great don’t get me wrong just would love more to do as I’m waiting for resources to collect or once I’ve built everything.
