This is for
@blueinsa as well
CK2 is free to play on steam so you have nothing to lose, however it doesn't hold your hand and you will need to go online to look at guides. Its also over 8 years old and it looks it! The interface is all over the place.
CK3 is included in xbox game pass for PC and you can pick up the 1st month for £1 so again nothing to lose.
CK3 looks miles better and although still incredibly complex it does a much better job of explaining the basics but again it can be a struggle to learn as there is so many layers. Coming from Civ you may have a slight advantage.
I posted a few videos for
@SWP's back and
@ultimateharold to take a look at a couple of pages back and i gave a few tips. The videos are really helpful
It can be really frustrating as you'll make loads of mistakes at first(even i have and ive got around 400 hours in CK2 which is nothing really!) but if you stick with and you get through the steep learning curve you'll find its one of the greatest games you will ever play
