Meh, I suppose The Empire/Imperials.
However, I really wasn't that engaged into Skyrim like most people. It was a bit too easy, even with difficulty cranked up at times, and I think the main issue I had with Skyrim was the combat was extremely bland. Most of them you would just win by randomly swinging your preferred weapon of choice with no thought, occasionally raising up a shield if you even had one (Or you was some MLGQuickshotPro and duel-wielded swords because, you know, thatsa what cool cats do these days). Magic was a little more interesting, but a little generic. Of course, there are the Shouts, which are a bit creative for the most part.
Maybe I've just been spoiled by good RPGs like Dark Souls, but oh well. I've been more of a Fallout guy myself when it comes to Bethesda's products.
