since its called skyrim maybe we should have like an airship or a dragon, maybe more available places to travel and bigger map like going to Cyrodiil again or Morrowind , Different types of horse. Some are fast, nimble and the usual...but also some that are bred for war. That can smash, or ram, into enemies, When blacksmithing you can build custom weapons based on parts- like a curved, wide or narrow blade based on your skill...maybe a something like a slider in the menu to help design the features, Stores that sell pieces of weapons or tools needed to make them. Gotta spend loot on something and You should get to lead an army, i hate the whole 1 man vs The potential destroyer of the universe, its total bull, theres always an army. you should just get like your own guild or something like that and your all dedicated to stopping the dragon and you can recruit more people to join you and you should get like your own fort or liek castle or village or something and something of the sort anyway and in the final battle there should be a bunch of like level 5 minions of the dragons that your soldiers fight as well as lesser dragons and then in the end you kind of take on the world eater dragon or whatever mostly on your own, or make an army.
I hope some of those would be included.
Thanks
