1. Remake the crime punishments
Most everyone would just reload the game rather then experience the feature thus its basically useless. Any feature that can make the game unplayable is a negative feature. Only death should make the game unplayable.
2. Bring a hardcoe mode for Skyrim
Food and water are abundent in skyrim this isn't a wasteland desert but a lush enviroment full of life and sense every single character in the game can summon fire from his hands keeping warm shouldn't be a problem for anyone. The food and water thing was meaningless in New Vegas it be even more meaningless here.
From reading the rising threat it sounds more like the Thalmor cowered in holes while the rest of their people suffered and died then after Martin Septim ended the oblivion crisis they emerged to steal the credit. Being Clever manipulating mages doesn't make them worthy of anything. That aside YOUR DRAGONBORN living proof that Talos Septim was divine there is no reason they wouldn't want you dead.
6. Own a keep, castle, fort or large city
I would love to be able to own my own stronghold. Having a house was never enough for me honestly. I like to decorate my own stronghold with its own defenses, guards, and buying my own large house and decorating it as I see fit. This was also my most favorite thing about morrowind and oblivion where you got to own your own tower or fighter's stronghold. Something like this alot of fans would love to see in Skyrim. Alot of cool buildings inside such as a temple to the divines (or some other entity depending on delights your fancy).
This I can get behind, I have a mage with a hundred thousand gold and nothing to spend it on. My only thought is to buy every spellbook(despite already knowing them) and stock bookshelves to be a magic library.
That is supposed to happen, but what happened to me was right as I changed into a werewolf I fed on the cultist, and then 2 seconds later I changed back into a human.
Certain cutscenes may force you back to human form.
