Which is ahistorical bullshit taken from biased sources. Which, the game isn't supposed to be education, really, but the fact is a lot of people get most of their history from it and think that's what Messalians really were. And the Zoroastrian bit's even worse since it's still a religion that people follow.
That is a good point, considering how much I've learned about Eastern Europe and Northern Africa. Stuff I was maybe quizzed on *once* back in middle school. Maybe.
The descriptions are nice, but naturally focused on mechanics. I grew up on games like Age of Empires 1&2 which had interesting historical information which was accurate and completely independent of gameplay.
And honestly, Alpha Centauri, which wasn't historical but really opened my mind to possibilities and consequences. I *think* Civ 2 had real life history, but I was too busy screwing with the scripting language
CK2 wise, though, I sure am glad it mentioned the Cathars. I've never heard of them from any other source, except when I went looking, which is amazing since they were the first target of Catholic purging. A dark time, not representative, whatever- they shouldn't be forgotten, and their version of Christianity is fascinating to me.
