2. More houses. I think it would be cool to have them in other towns apart from the 5 they are already in.
3. Add new places. I am new to Elder Scrolls, but I think they should add some of the places the older games took place in.
4. More NPCs. Sometimes a dragon has taken out a good majority of a city, and it leaves very few people (besides guards) left. I also think if the owner of a shop dies, they should get someone to replace him. (One time I accidentally dropped a Fire Rune in the shop at whiterun, and the stores been closed since)
