I can go anywhere I want. The question is increasingly why would I want to.
That is exactly how I feel with Skyrim. There's a certain balance between quantity and quality that is needed, and I think the scale is tipped too far towards quantity. There are over 400 quests, but most of them feel exactly the same. There are many unique locations, but no unique loot. There are dozens of different shopkeepers, yet most of them say the same exact lines. There are many NPCs, but most are either Nords or Imperials.
That's actually my main gripe with this game, with regards to race. There aren't enough Khajiits, Argonians, etc. Almost everywhere you go, the area is full of Nords and Imperials. Why couldn't there at least be a small village full of Khajiits, Argonians, Orcs, etc.?? Sort of like an 'Island for Misfit Toys.' Maybe even have quests with them to rise up, band together, and crush both the Imperials and Stormcloaks. That could have been very interesting. Or at the very least, the village could just be a place to go to get away from all the Nords.
Like others have said, I feel that Skyrim was rushed. If they didn't have their sights set on 11/11/11, Skyrim probably wouldn't have been released for at least another six months. The game is ridden with bugs, there are so many areas that feel so dull and empty, the guild questlines are too short, not much variety at all in NPCs... I really need to get a good PC and take advantage of the modding capabilities. Maybe one day...
