I'd like to be able to set multiple citizen on improved tiles, it would also help to determine a more detailed city social stratification, but I don't think it's possible for improvements, adding citizen to a district for example seems to be hardcoded to buildings, it's not a modifier AFAIK. I really need to come back on some of the post about designing the research, the unit tree and social stratification BTW, but I'm still coding the background for integrating multiple equipment types/classes for units. While doing that, I had a possible idea, related to equipment and standing armies (or lack of) for early game. What about temporary units ? You could have an (initially) very small standing army limit at the beginning (say 2-3 units) But you'll have some stocks of equipment and (of course) some population in your cities. Barbarian (or neutral) units approaching your territory could unlock a one-turn project in a city for conscription. Next turn, some units (number and type based on equipment and population) spawn around the city for your civilization, with a counter before disbanding. When the counter is down, the remaining personnel and equipment is sent back to the city. We could have (longer) projects to plan for an invasion or cleaning that barbarian camp you've scouted, with a bigger counter for units, depending of the project. thoughts ?
