App like habitica, but a medieval town-builder

I have an app I'm working on with a friend - it's a habit-management city-builder, where as you work towards your goals your city improves.

Towns have three parts, a military area improved by completing fitness goals, a science and magic sector upgraded by mental effort like studying or learning a language, and a production area with mines and farms which would be improved by tasks like cleaning your room or planting a tree or washing the kitchen.

We're still in the very beginning stages, and have lots of ideas for further down the line (soldier expeditions for resources, trading with other players / settlements).

Is this an idea that excites you, what possible features come to mind?

Thanks for any feedback!
