Okay. I really think you're just nit-picking my post.
Exactly. A problem that would be fixed if they made a CK3 because it presumably would be 64bit from day 1. I:R is 64bit. Stellaris recently dropped 32bit support.Untrue. It is perfectly possible to update existing software to be 64bit. In fact, many software companies do exactly that. Paradox just doesn't want to invest the time in doing so for CK2.
Last I heard, it is hard-coded in the game. Which is the reason why modders haven't been able to do it either.This has nothing to do with engine limitations. Theocracies being unplayable is a conscious design choice, because the game is supposedly about dynasties.
Yes, but over the long term it will be faster. So my point still stands.A new engine if anything will only worsen performance, because it hasn't been profiled and tweaked for as long as CK2's to extract the best performance. You will have to start the profiling and tweaking effort all over again.
