I am still gonna... buying it for a while
lol wtf cuck
Unless it's in a Humble Bundle on a MASSIVE discount
This is a ramblepost, but something I thought CK2 could have actually used work on, surprisingly given its focus, was better traits and personalities.
The problem I had with it is that, at first, the characters are really neat, you can look at them and read off it what they're like as people, compare them to others, use the traits to roleplay. When it's new to you it's interesting. But the problems soon accumulate, mostly coming down to that characters have WAY TO MANY traits, they don't flow together in any coherent way, the individual traits appear too often (cheapening their meaning), and to some extent they're a bit too malleable (it's so easy to powergame a genius commander into existence stacking +Martial skills).
I don't know if CK3 is any better in this regard, but there were some mods - abandonware, of course - that tried to improve this. One of the better ones had this idea of using humor theory as a thematically appropriate personality typing system. If you don't know humor theory, the humors have one axis of "hot and cold" (basically extroversion vs introversion) and "wet and dry" (basically pleasure-oriented vs serious). Like every personality typing system it runs into its limits, but I find it genuinely superior to the ones we actually use in the contemporary world for understanding. Well, this one mod (don't remember its name) would have a character have one or two temperaments and that would in turn decide what traits it was able to get, so you could just by glancing at a character get a general sense of what they're like without reading the word soup of all the different traits.
My own thinking was it could have been made to work around nature and nurture. From each parent you inherit an axis (like a chromosome), and the combination gives the nurture temperament (parents with diametrically opposing natures, like a phlegmatic and a choleric, could have ANY). Then, characters around the child in early life (namely guardian) have a chance of transmitting ONE OF their own temperaments as the nurture. Then, the character's combined temperament determines which traits they have access to.
Add on to it traits being less frequent and tied to major life milestones (ascension to throne, first marriage, first child, etc.), and coming in different levels. Levels I imagine as "mildly, moderately, severely" and being like Bell curves with rapidly increasing trait effects, and also being less malleable as you go further in one direction, the severe ones being straight up pathological (like disorders) and unlocking trait events that go with that (ambitious men with god complexes, paranoiacs that see assassination plots everywhere, gluttons that turn into 300 lb landwhales, that good stuff).
How do I justify the post, eh, I think this sort of thing is ultimately better for roleplaying than the bullshit for Tours and Tournaments is.
