The Spiritual trait probably needs to be cut, and likely replaced, because
1) We replaced religions with cultural groups, which cannot be spread manually.
2) There are no temples. We've considered adding ghetto or slum buildings, but they cannot be built under normal conditions.
3) We extended revolution length as a way to produce a more realistic situation, and ensure that big events like China becoming a democracy can't happen overnight (If you don't like that, don't blame me, as I didn't support going that route, but I was outnumbered), so the Spiritual trait would unbalance the game.
So what should we add instead?
