I'm just wondering... Because seriously, what wouldn't make you happy if Skyrim couldn't?
Well since you asked...
1. Being able to mix my own potions WITHOUT having to detour to find a alchemy lab
2. Less bugs-yep characters feet are still disappearing through the floor, voices cut off, screen freezes, quests go unfinished, scenery disappears
3. If i am going to be fighting Dragons: the large, powerful mythical beasts should be a little harder to kill compared to a frost troll, bear, giant, random bandit warrior...
4. Better menu system. I don't know about anyone else but the map and menu are horrible. For those of us not playing on a 50 inch plasma tv; the dark, tiny menu script is a nightmare to try and see.
5. Better levelling system. Bethsda tried to fix the problems from Morrowind and Oblivion, but nope, still not quite right yet.
Those are just a couple of my personal qualms, but hey not everyone may share my view, unlike you i accept that. While Skyrim is an excellent game you can not complain if people want to discuss a few flaws, this is a FORUM after all, a place to put forward opinions and ideas. If you love or lothe something it doesn't make your opinion any less valid, just different.
