Skyrim itself is great, in terms of content there is so much to explore and the landscape of the game is fantastic.
Skyrim's PC treatment however, is poor. It looks and feels like a console port. The menu system is clearly aimed at console users, and the graphics simply do not tap into the power of modern PC graphics cards at all. My first play of Skyrim felt like I was playing something from 5 years ago. I had to tweek the graphics options a lot before I got anything half decent out of it.
I still play Oblivion now and then, and the graphics and interface seem a lot better than Skyrim in places! This can only be explained by the fact Oblivion was designed for PC, whereas Skyrim is aimed at console kids.
So yes I do think that PC users get a raw deal here. You expect better graphics than XBox 360 users get, if you have a PC with a top of the range graphics card with DX11 support. I have PC games from 1 or 2 years ago which have far better graphics than this!
Some better usage of the PC keyboard would have been nice too, instead of having to scroll through menus here there and everywhere. Keyboard shortcuts anyone?
These flaws aside, Skyrim is worth getting. But in so many ways, as a PC game, Oblivion was better!
