Well at face, this just seems like an opportunity to argue. There are a couple things I feel the need to point out though.
First, the claim that FONV improved over FO3. It's all just a matter of opinion. The way your character moves, jumps specifically.. still svcks. No improvement there. The map itself, actually took a step backwards. It didn't feel "open". You could go up the left side or up the right side with things off to the sides a bit. Just felt like two channels. The graphics, were pretty much the same, no big advancement there either. All in all, I'd say NV did not improve at all.
Now did Skyrim improve? In some ways, yup it did. They made changes in areas that they felt would attract to a larger crowd.( I even remember noticing some things from FONV in Skyrim , can't think of them now) Is that what they should do? In my personal opinion. Heck no! But from a business stand point, obviously yes.
And as far as the cosmetics of the ink blot test determining your path. Come on. It's a simple smoke and mirrors to look pretty. In the end you are still given the opportunity to say what you want. It isn't some big amazing thing. And really, is it needed? I doubt it. So many people complain about being stuck in one aspect.. and so this is what we get.
I love Skyrim. Does it feel like original

? Nope, not to me. But I still think it's a great game.
