Out of the bajillions of mods out there for Skyrim, I’ve yet to see something close. Sadfeels

They literally put in the Blades, the personal army sworn to the Dragonborn, and didn;t let you do anything interesting at all with them. You can’t even tell them what to do unless you kill a cool dragon

I think the first time I actually realized that Skyrim fails to be a proper “wish-fulfillment” game is when I couldn’t do anything about the Reach. It ends up as Nord Rhodesia/N.Ireland regardless of what you can do. (And, of course, the usual lib bothsideism of making the Forsworn just as bad as the colonists).
