I'm not sure there's a "standard." It's more of what settings you like since it's mostly a single player game. There really isn't a competitive scene where rules would need to be standardized like you're trying to get the highest score. Score generation in Civ 6 is kind of a poor metric anyway, IMO, since getting a higher score often means deliberately trying not to win quickly. Anyway for me: -All official content enabled: RF, GS, NFP -Seven Seas or Continents + Islands Map, Standard size -Emperor difficulty -Disasters: 4 -CS: Hattusa, Mohenjo-Daro, Vatican City, and Mexico City off (I just don't like their mediocre bonuses) -Nat Wonders: Bermuda Triangle, Fountain of Youth, Paititi, and Mt Everest off (no fantasy ones and Mt Everest is so unrewarding) -Shuffle Tech on I'll occasionally overload it with +1 civ. I do like the Barbarian custom, but it's got its problems The Monopolies custom is ok, but can be game-breaking b/c the AI doesn't use it well and I frankly hate having to sacrifice GMs for corporations. Dramatic Ages just destroys games. Civs that get behind get so far behind so quickly they can't ever break out. Game is realistically over long before it finally ends. Until they get some of the game modes through a few rounds of balance patching, I'm not interested.
