What works for you about the Religion Game in Civ VI (or in previous iterations of Civ)? What doesn’t? Looking into the (possibly distant) future for Civ7, what would an ideal Religion game look like to you?
In 93%* of my games, I don't found a religion. I actively pick slightly bigger (standard size) maps to play on because i don't want the AI to poach a religious victory from my inevitable cultural victory. I also tend to pick crazy religious AI opponents (excepting Peter) because I know they are less likely to compete with culture and I have no desire to compete with them on religion anyway. So that's how religion typically affects my civ 6 games.
Now that wasn't your question. I like the mechanisms of founding a religion and I like that the number of available religions in a given game is slightly limited. Some of the religious benefits might be over powered (*cough* work ethic). I think the way religion spreads makes sense, though religious combat for the AI might be more broken than regular combat for the AI - a good player will destroy the AI in religious spread or regular combat.
I like the "cultivate, not spam" comment. Tourism (well, until rock bands), is kind of a cultivate, not spam victory condition. There is early cultivation of religion, but ultimately, you are trying to overwhelm your opponent. And there are too many ways to goose your faith production to make spamming not pretty much inevitable. Think if there were science or cultural equivalents to pantheons ad religious beliefs - really, you're going to make my theater squares +12 or +14 or +16 culture? And then you are going to convert that culture into production as well? yeah, that should work).
Peter religious victory, Peter cultural victories, Peter science victories, and Peter domination victories are fun (I will never claim a score or diplomatic victory is fun), but come on, man! Peter exposes pretty much all the current issues with religion in civ 6. And while Peter, specifically is a bigger problem than other civs, Mali, Pedro, and others can exploit the religious systems in some pretty extreme ways as well - they just don't have 40% off holy sites.
*Completely made up statistic, put probably close.
