What did CK2 taught me about history? My answer is: not enough. There should be more historical events and/or some summary about the state of the realm you're gonna play in. Right now it's just encouraging me to learn more and that's not enough. I'd prefer learning through playing. Not after or before.
I agree
I remember, in Rome I Total War, Barbarian Invasion, they had events pop up in historical dates. It did not do anything, but it told you what happened on that date. It just helped show what was happening in that time.
You could for example have events pop up when your playing, speaking about certain schisms that occured, or any wars, or the date the crusades started. thinks like that.
