One of the big issues of EU4 is the complete lack of internal factors that can drive a country. Theres no nobles to deal with, no politiking factions with their own vested interests, different cultures are just colors on a map, and the penalties of different cultures neatly divided into 'Accepted Culture', 'Same culture group', and 'Different culture group'. Revoltrisk is almost entirely raised by war exhaustion, overextension, religious/cultural intolerance. Religious difference penalties are entirely cut and dry with the 'Religious unity' and 'Intolerance' penalties, and most important of all, provinces are universally monocultural and monoreligious.
For these reasons, theres very little to do at peacetime, and very little work in maintaining a large empire once you got the cores established, just random events the game throws at you from time to time that are, most of the time, completely detached from what is actually going on in your empire. One of the more extreme examples is when I converted Sweden to Shiite, and the primary culture to Tartar, and gave away the Swedish lands to Norway. Despite completely replacing Swedish nobility with Tartar nobility, aside from the -5 stabhit on culture switch and the prestige hit for force conversion, nobody batted an eye.
