I want a sort of civilization-but-for-countries.
E.g. you are the newly elected president of Afghanistan/North Korea/Iraq/Other etc - now go rebuild infrastructure etc, set policies, see how the country develops as a result. E.g. do you invest in universal healthcare, or transport infrastructure? Is transport infra required while your country is still largely subsistence farming?. What about education - save money there and spend on natural resource extraction? How will that play out over decades and centuries?
It would be nice to have direct control over city-level layout etc - demolish this neighborhood for flood defences, put in railways, major roads etc linking different parts of your country (not sim city levels of simulation, more just at the major civil engineering level of that makes sense - happy for actual city population to grow organically as a result of major works).
Civ gets close, but it's too high-level and more focused on conquest. I want to zoom in and have more control over where major irrigation canals get built, where to best build a nuclear plant, where that bridge should go or which mountains to tunnel through for a railway etc. So instead of the grid being the entire planet, the grid would just be one country.
Edit: I am specifically interested in the "building" aspect (so think civ-style grid with units moving around doing things), and less so on simple a-vs-b decision game model you see in Democracy et al.
