Just about to finish my SEA campaign, I'm waiting for my current character to die so I can finally hit Godlike piety
Overall, it was pretty fun, but the 10 feasts requirement for the Aspect of Serenity were pretty annoying to get
Just a lot of sitting around getting tributaries and vassals diplomatically while waiting for the 5 year cooldown to end.
90%+ of the land I have, I didn't even conquer
Honestly, it was the region I was least interested to play, but it turned out to be the one I liked the most with it's unique mechanics.
I would recommend you try it once with one of the other paths, unless you, for some reason, really enjoy spamming hunts, feasts and other activities while constantly using the befriend scheme
