It is not just about deity. I think, it has much greater impact on emperor and immortal, which gain another, less restricting (in terms of gameplay) alternative to rise difficulty. I agree with you 100% ... in an ideal world. There you receive the needed ingredients & tools. The final words on the civ6 DLL sources are not spoken yet. Though I plan based on what can be done in SQL & Lua (prolonging the challenge). Probably 'develop a better AI' and 'a less passive AI' is just a nice idea, sadly. So you can dress Barbie in and off whatever you like all day long, but she denies to learn any new tiny song or move. A limping beauty if you look close enough to break your heart. Delaying the point where the challenge disappears is better than nothing.
