Hello, I’ve started my first Ironman run. I have about 100 hours of playtime and own all the DLCs. My goals are the achievements for forming the Caliphate, "Definitely Rum" and "Parisian Pasha." My questions are: Which Idea groups should I pick for an aggressive playthrough? And how do I avoid falling into decline? Thanks!
