Dissapointed? Nah. Worried? Yep.
I've always loved the Nords, and I always thought that their culture is pretty interesting (What with the constantly-drunk populace and the constantly-sober-ultra-powerful-screaming monks (A.K.A. Thu'um) there should be an interesting contrast), and the enviroments are surely awesome. After all,
The Pocket Guide to the Empire, 3rd edition wrote: Skyrim is the northern province of Tamriel, a land of breathtaking beauty and lethal winters
However, I'm afraid that it'll become either
-Bloodmoon Mark II, as the enviroments will be pretty much the same, and will (possibly) get extremely boring, extremely fast. I want to see something that can't be described as "Huge chunks of rock with snow on them", Bethesda!
-Intransitable. I expect Skyrim to be mountainous, and I thus expect, y'know, to be able to go over the mountains, and not have to circle around them like crazy. This could be achieved in various ways, like, for instance, bringing back levitation from Morrowind, or even bringing back the Climbing skill from Daggerfall (In a less bugged and more actually plausible way, for those who don't want to ruin their roleplaying by having a dumb warrior who has access to one of the most complicated spells in existence)
You thought Dark Elves wouldn't ever rule the world. You where wrong.
