Yes, really needed indeed. As culture is in game an influence meter, it definitely should reflect the power of the settlement, so the minimum of artists rep & painting rep is definitely not enough. I suggest as OP an additive points system in different categories. Economical influence : - Settlement production / day, with scales - Trade volume / day, percent of global trade or fixed scales - Foreign trade volume with scales - Monopoly maybe ? (bonus for having the only stores selling a product : would push a settlement to specialize, other settlement to rival) Cultural influence: - Cultural buildings (I would give any settlement owned building this category) housing value, and maybe add something for total volume and room levels also - Painting, Sculptures & Decorations on cultural deeds : base value with their housing bonus (to include outdoors) and reputation system bonus Political influence: - Raw number of active citizens - Active laws, titles, districts, sub-settlements - Maybe a bonus for participation in elections (incentive to play an active role in city management) Prosperity : - Total XP bonus of citizens (food + housing, kind of happiness meter) - Total citizens reputation (instead of mixing with artworks) - Number of professions & levels
Giving a city culture for people coming from outside and purchasing stuff from stores would also help reflect trading/commerce powers of real life cities and indirectly help food and even simple material trading become more impactful in the long run, with more "higher quality items"(based on ingredients used or level of skill required?) giving more culture.
Yes, settlement culture should be based on knowledge and productivity. Perhaps it could help to push more than one char per specialisation per settlement. And perhaps there could be specialisations that don't add anything to productivity, which would represent the luxury of culture the best.
Perhaps requiring settlement/country to have even more reputation to push into the borders of neighboring culture spheres. This way 1 new painting or additional rep doesn't flip town B's tree farm over to town A. Let the initial spheres sustain their border and only after excessive culture difference will it start pushing in to other establishments.
The culture system will be expanded with future updates, this was just the start.
Having something like this attached to food bonus might help the food market stay strong mid to later game.
Great
