Gonna be awesome.. the landscape is much more detailed than Oblivion, no comparison from the shots I saw. As for the story, I don't play this game for the story.. well I do but I'm more interested in treasure hunting / exploring caves. TW2 is a great game but your very limited in your exploration. In my opinion the two can't be compared as they are different style games (despite being RPG's).
I cant count the times people open threads asking for RPGs and they specifically state what they are looking for, and people simply go in and post their personally favorite game, which is not what the OP is looking for.
I personally want a game to Deliver me the depth of story expected in a good RPG, and dynamic characters with a changing storyline based on my actions, along with an open world that i can run around in doing whatever i want.
perhaps one day we will get both in 1 game. Skyrim will be fun regardless though.
