Idea: Countries. Divide the world in countries, with different cultures, religions, politics, etc.
How would the culture and religion would work: There would be different cultures/religions in the world, one for a country. They wouldn't be obligatory, but would serve as inspiration and/or lore. For example: I want to make a temple, but I'd need to have a religion/culture. Since irl religion/culture is polemic and would probably cause problems, and a person would have to create a religion/culture only for that building (maybe others by them, too), having several bases would be good.
It would also be good to locate a building. For example: "My build is on (Country name), at the northeast region".
We could have more events too, based on the religion/culture festivities. For example: "October 27th is (God name) day".
