Skyrim is in my opinion the best TES game, however there are some things from the other games i am missing: -Armor slots like in Morrowind, the options there were plainly insane. Expecially from a modding perspective. -Classes. I think that skyrim could have had a system where you could freely pick and change classes. the only difference the selection of class would do, is highlight where you should spend your perks, and perheps a small bonus. New system is great, and this is probably going to be included in a mod. -UI more like Morrowind. Dont get me wrong i like the skyrim UI, but i would love an upgraded version of the Morrowind UI. Other than this i feel skyrim is a major step forward for the TES series.
