1.) -Skyrim looks boring everything is snowy and mountainous-: It doesn't all look the same! The western parts are Canyons a slightly forested, kind of like Hammerfell. The southern parts are forested as well, only about half of the place is dreary ice and snow. Lore not enough for you? I have caught a glimpse of Skyrim from vanilla Oblivion, a small glimpse. Don't believe me? FT to the Blades place north of Bruma. Exit the castle and head north. You should see two peaks to your left and right with a mini-valley in between them with boulders in it. This can be passed! Go as far up the western slope as you can, and stream along the peak's side heading north. Eventually you should drop into the flat part of the valley. You can also se the mountains beginning to curve back down to a lower elevation. Head more north in the valley until you hit the dreaded "You cannot go that way. Turn Back" sign. About in the middle of the valley, lok down towards the 0 elevtion ground That is Skrim. you can't. HOWEVER, at one area in this little valley, You can see the tops of green trees, and they aren't pines. Forests that aren't snow-ridded exist in Skyrim!
2.) -It's Nord Country. They are a barbaric people that are nomadic with only a few towns and countless dangers. Always at severe risk of getting killed doesn't sound fun to me" take a look at the lore. There are several cities and civilized Nords in Skyrim. For example: There is the city of Winterhold, organized, Empire safe, and big. You'll be about as safe as you were in Morrowind.
I could go on about this but I won't to keep this short. Hope you have realized something!
http://elderscrolls.wikia.com/wiki/Skyrim to prove the climate is not all snow and ice. While snow and ice are the dominant kind of climate, large areas, especially in the south and west, are flat and vegetated. And the snow and icey one aren't just snow and ice, you'll find plenty of flora and fauna inhabiting those regions.
