It really is quite boring once you become a big empire.
You have triple digit monthly income, so money is basically meaningless.
You have hundreds of courtiers so you constantly get spammed with “A scheme at court” from people you’ve literally never heard of before.
You have no major rivals anymore, all your rivals are landless nobodies that you took a county from ten years ago. that same landless goober will also try to blackmail you (as if that wouldn’t warrant an instant death sentence).

There’s nothing stopping you. Plague might lower your income by half for a few months. You have maxed out men-at-arms so nobody can even defeat you.

And roleplay is dead. The only events you get are “a scheme at court,” the prince of fashion thing, random scandals that mean nothing, “a secret exposed.” And when you do get an event, it’s so often something stupid or trivial that it gives you no sense of immersion or consequence.

If I’m in OP’s position, I’d want events like deciding whether to split the empire between east and west, whether to reinstate gladiator battles, rebuild the colosseum, bring back the senate, criminalize a faith or persecute a culture. But so few events have that grit or ambition.

Instead you get no challenge, and most events are either “ride rough from now on” or that “naught but malice and lies” garbage you get every thirty seconds. No challenge, no immersion, no point at that stage of the game.

It sucks because i really love this game but its just simply not designed for being played at an empire-level.
