I feel kind of bad, considering some people clearly worked hard on the looks, but currently I'm not sold either.To sum it up for me:
- UI look bland, uninspired and minimalist
- Characters look cartoonish
- Map looks empty and lacking color
So, if I have few concerns regarding the mechanics - as CK3 is being built on the shoulders of a giant by the same designer - I am not sold in the least at the graphics in their present state.
I think that graphics have been proven as really important in ck2, with many graphical updates release over the years and people pretty much demanding every original face replaced by better ones.
Updating these won't be as simple as making a portrait pack :/
