People are complaining way too much.
Yes, I hate the UI with a passion. Yes, I blame it on consoles.
Yes, I had mouse-lag. Yes, the FoV is ridiculously narrow. Yes, there are more little issues like that in the PC version. But I don't care. There are easy ini-changes to take care of that. Those problems are small and will be fixed soon, either in patches by Bethesda, or with ini-changes and mods.
But the game itself is pretty sweet. Technology-wise, I don't think it is a big step up from Oblivion. But would you really want a Crysis2-like RPG ? Nope. I rather have a good game with Oblivion-level graphics. And that is what we are getting here. I have played only for 2 hours. But I was enjoying myself. The landscapes looked beautiful. The animations aren't perfect, but a big improvements over Morrowind/Oblivion. The voice-acting was good (I wasn't annoyed by them, so that's good).
I've been postponing to upgrade my system. E8500, 4GB ram and a GTX260. I'm running all sliders at max (including Ultra shadows), with 4xAA. I am getting 25-60 fps everywhere (1920x1200). Good enough for me. Only when plugins with lighting changes and ultra-high textures come, I might need to speed up buying my new machine.
So far, I am impressed with the game.
