Well right now i am playing this mod:
http://www.moddb.com/mods/nehrim-at-fates-edge
...kinda makes game better with xp system and saved skill points. Its pretty much a new game. Only downside is that it has some sound problems (bzzzz in some areas so you need to disable sound), crash when you enter a new door area (you gota save on every door) and escort main quest (loooooooooong walks).
Questline:

Playing it for a good week and still not finished. Map is pretty big to.
(there is no fasttravel--but you can buy teleport to city skill that consumes a item)
