@JubalBarca this was always my issue with games like Crusader Kings where you’re either a vassal or you’re not, and there’s no model for ‘vassal with respect to this territory but not other territories’. (Brandenburg-Prussia comes to mind as another example and I’m sure there are countless others.)

But it’s sort of forgivable in a game; they need to balance accuracy with playability/fun. It’s more concerning in something that purports to be factual.
