I hope to see many things... 1) more mounts and mount functionality. I'd love to be able to fight off horseback, delivering devastating blows with the increased power of the mount, etc. 2) More armour designs. Oblivion had way too few. Once you finally reached daedric armour, there was no reason to use anything else. There needs to be many different designs of armour that is comparable in quality. This gives you much more creative freedom without sacrificing protection. 3) More interesting NPCs and deeper NPC interaction. Like others have said previously. 4) Way more followers. I think the max was like 4 in Oblivion. It would be awesome to be able to form a group of 50 or more! This would be dictated by your fame. I think once you've reached a certain point of fame, you should be able to have a small army to fight for you and to guard your residence, etc. Just like a medieval lord. 5) Arena tournaments. The arena quest in Oblivion was kinda lame. It would be nice to increase the number of competitors in the Skyrim arena quest. The quest also should involve touring to all the cities in which they have a championship event at the end. Once you've finished the quest, tournaments should be held every once in a while in which you get to compete for a great deal more money and fame! Sounds much more interesting doesn't it!?
