I proposed above a UA that grants experience to all current and future units on adoption of a policy, giving you experienced units in the late game, but being active from the start. And giving xp to units far away scouting and sitting at home.
OK. I guess I don't really see any particularly good flavor or gameplay synergy here.
It's very capital-centric, I think that strongly favors Tradition and Tall. Many of the Tradition policies are all about a super-capital.France was wide in Vanilla and is still in BNW (the chateau!!),
I think it does. Being tourism oriented and policy-producing oriented are not the same; the former favors wide, while the latter favors tall, because of the per-city culture cost increase for social policies. It also means that you get a tourism benefit from the various sources of free culture: oracle, Sydney opera house, the Ideology luxuries, contributing to world fair and international games.The flavourful comment was mainly directed that tourism-for-policies is "culture/tourism from culture" (same from same) and that it doesn't change the way you play.
The French AI in BNW also seems to be playing Tall/peaceful in the two games I've seen them in.
Too strong or not is all in how much tourism you get from the ability. I don't think we want a France that benefits from having dozens of empty (=no great work) amphitheaters, opera houses and museums.I did want to limit it to culture buildings to not make it too strong.
We also have some control on the total number of policies, and rising marginal costs for each. Whereas it could be easy to spam small cities with culture buildings and generate unbounded amounts of tourism.
