If I pump up the game difficulty to Hard or Very Hard, what exactly does that do? I've seen in another thread that vaguely explains that you get more crappy events, and it's harder to grab claims (more prestige is required). Is that all? I want to stick with a challenging but "fair" setting, so if the AI lords are arbitrarily aided in some way (their vassals are more loyal than my vassals, or something), I'd rather stay at Normal difficulty.
