I have played TES games since the Arena days, and I distinctly remember how BUGGY Daggerfall was on the release date and a good time afterwards. WAY more buggy than this game sounds. Bethesda is not like Blizzard, who tend to be perfectionists when it comes to the quality of game on initial release. Anyway, Daggerfall was almost unplayable at launch, but we were much more patient back then it is was quite common for software to be buggy when first released to the public. Not that it was right, but it just was the way it was. And Daggerfall became one of the great RPG games. In fact, many TES PC gamers consider that game to be the gold standard of the TES universe.
I am a bit concerned about the port /menu issue, and it does make me hesitate to run out and buy the game when the time comes, but overall, I haven't heard anything negative in terms of the experience within the game, mostly because it is too soon for people to judge at this point. In addition, human beings tend to like what they are accustomed to, not necessarily what is right or good or beautiful. The menu controls may be a little difficult to get used to, but lets here what people say after a week or two of playing the game.
