Me;
-werewolves, werebears and wereboars: all are lore correct for skyrim and after 5 years of developtment atleast one of these should be available.
-more than 8 voice actors, I only noticed recently that every character in oblivion had the same voice depending on race/gender, atleast give main characters their own voices.
-all the races, I know they'll all be available but I'm worried Bethesda will leave races such as argonians out because skyrim will be "too cold"
-morrowind style enviroments, I mean as in each region of the game having it's own look like ashlands were distinct from bitter marsh region which was distinct from the grazelands whilst oblivion was just different trees and tilesets for each area, eg. Colovian highlands were only distinct from heartlands because it had different trees, more yellow textures and was hilly.
-morrowind style cities, as in open cities with truly distinct architecture and stuff, more aesthetic stores like jewellery stores, clothiers, pawnbrokers, didn't see too many of these in oblivion
-more varied creatures, like morrowind had practically double oblivions.
-populated roads, I want to see caravans, merchants, wanderers, adventurers. Not just the occasional imperial legionnare and marauder.
-populated cities, in oblivion the cities to me felt like they had about 20 people in them.
-varied waterlife, not just slaughterfish!!! Atleast some damn horkers atleast.
-wildlife, like birds, butterflies, foxes,
-more unique weapons and armours, like in morrowind which had tons of unique looking weapons and armours. My morrowind artifact collection put oblivions to shame, with it's meager collection of about 20 unique models compared to morrowinds atleast 50.
-better characters. More hairstyles, more eye colours, better body models, real facial hair NO TONE SLIDERS! My character wants a beard! Not some black smudge!!! Oh and the option to make a character look half decent easily without mods or spending an hour on the race menu.
