This discussion will really lead to nowhere

. It is NOT obvious that cultures don't have much potential in this game. That is just your opinion and I have mine.
I think you also didn't understand what I meant regarding the core system. I hated it that some countries have cores on provinces with a different culture (in reality) and others have no cores on provinces with the same culture.
Edit: Let's not argue over the topic if we should have cultures or not, ok?
But everyone, if someone wants to have them please say something. Thats the question of the topic
