What are the most difficult mods to play?

[highsis]

I've never played anything other than the poorest of poorest count but the game feels incredibly easy in vanilla or mods I've played.

I want a mod that is really challenging with features like internal defensive pact(vassals join against other vassals expanding), difficulty to expand and climb ranks, difficult economy, non-faction vassals can join faction rebellion at cue, etc that makes the game harder overall.

I usually play CK2+ or HIP but I'm wondering if there are more difficult, fun mods out there.

I want Magna Mundi equivalent of CK2. Role-playing is fun at all but every game as a count the emperorship is practically granted. I need a challenge! (not sort of challenge of crippling myself with house rules or doing a challenge with specific goals, I just I wish regular gameplay were more difficult so each step to the power is a challenge itself.)

You can cut the demense and vassals limit by half in game rules before start of the game. This should make things more difficult.

Western Europe 410 - 962 The Winter King, i'd suppose, though depending on the party you take.

Potentialy the now outdated War of the Roses, aka Western Europe 1469 Alpha on patch 2.3.6.
Don't recall the mechanics though..

The Winter King and Lux Invicta, I think
