This is a question that is asked often in the Anbennar subreddit (Yeag I know ). The most common answer is that people with lack of EUIV experience who want to get into Anbennar are better off starting with playing Anbennar so they can familiarize themselves with both the base game's and the mod's mechanics simultaneously. I think the same thing, there are many tooltips in the custom UI that explain everything, so don't worry about having to pull up a wiki every time an event popup happens. (In fact the wiki doesn't even contain gameplay mechanics anymore, just L O R E)

But keep in miiiiiiind, Anbennar can be harder than EUIV and some parts of the game expect you to have a deep understanding of the mechanics, after 3000 hours of EUIV I can't confidently say I could play the most difficult countries. So what I'm trying to say is, do not be afraid to cheat. I mean, the A.I. already does it, and player enjoyment matters more than anything. So if the going gets tough, or you just don't want to wait 50 in-game years to see the next mission and event cause you missed an obtuse mission requirement, just pop off with the console commands!
