Hey, I've started very late with Civ 6 and have a few questions. What happens with Great Prophet Points after you get your first prophet? Do they just become worthless? In a recent game I kept getting the message: "Your culture has grown sufficient to dominate such and such civilization" - I don't remember the exact words, but something to that extent. What does that mean and what do I do with it? Is a culture bomb just a bunch of culture in the city? Thanks.
