With the fourth dev diary we may have seen the first trait that might be included in CK2...
Looking at Edward III's character sheet, I would venture to guess that the traits are represented by the row of three icons directly below the dynasty arms. If that's correct, we can also see that the first icon is a rectangular shape (as with the education-granted traits from CK1) while the other two are circular (as with event-granted traits from CK1).
We can also see that the circular icons contain numbers within them (a 3 and a 2) - perhaps representing different degrees or levels of traits? Remember that CK1's education traits were all granted in various levels depending on factors such as educator stats and capital province improvements.
Finally, looking to the right, we can see that one of Edward III's vassals (presumably the Duke of Cornwall, also called Edward III) has a positive relation modifer due to his liege (Edward III, King of England) being "Diligent" - which I would guess is one of the traits represented on Edward's character sheet.
So there's a bit of guesswork and inference going on there, but what traits would you like to see in CK2? If traits have different levels, how do you think that might work?
Personally I'd like to see all of CK1's traits reappear in some form, though a trait like Diligent could replace CK1 traits like Energetic. Hopefully traits will be easily added and removed via modding.
