What did you think they improved in Oblivion over Morrowind??
Personally:
-I Like that fatigue is not lost when running, not wonderful for immersion but way better for game-play.
-I like skill perks(most of them anyways).
-I like the option of Fast Travel(I think it should be more limited then it is. Just being able to travel to regions rather then right in front of the door but alas).
-I like castable staves.
-I like offensive potions.
-I like being able to buy and own houses(although I think they should be more customizable).
-I like being able to ride horses.
-Aylied ruins and such, love the atmosphere of those places!
-Way better combat! Not perfect but certainly better.
-Regenerating magika.(Even if I play under the atronach)
-Better animations.
-Better Journal.
-Longer Viewing Distances
-Ummm... Thats all I can think of for now..
