Could also be redesigned to become a bigger part in affinity victories. ^^ Would even make sense, the "ideology" of your people has so much more to do with their culture than just their scientific advances. I'd actually say pushing Harmony further towards culture, Purity towards production and supremacy towards science would make a lot of sense when it comes to "flavor". But of course, a lot of mechanics would need to be redesigned around that.
I had thought of making a mod that added projects that increased affinity and change the wide virtue synergy bonuses to be free affinity levels to give more ways to get affinity. I hadn't thought of making these different methods specific to affinities though. I don't think I could give specific affinities through virtues anyway.
Not going to to a lot of modding with an expansion on the way. Just going to finish what I've already started then wait and see.
