Goord Lord no.
I loved EUIV and I played it death, but having now finished with the game forever (bored, the Emporer update which I dodged is a disaster by all accounts), i'm definitely not missing how it looked, it wasn't great graphically and the text was an absolute nightmare to read. HOI IV lost me in development when theey were clearly not going to allow the "Battle Order" military structure system I loved, but it does look graphically reasonable, if a little arcadey and and simplistic. CKIII looks really nice, it is graphically appealing in its own way, although I know the "toony" style isn't liked by many.
But none of them are a patch on how Imperator Rome looks, especially the map, which is gorgeous, it's issues graphically are wthin the UI of the game not it's presentation.
