You are not getting my point.
At first I just loved the new scenery, the greatly enhanced visuals, HDR and the like.
I even made a mod to help me more into the game and believe it or not, it was called "Pure Immersion", and it would relieve me from power-gaming to gain those 5-5-5 attributes in the level-ups, and let me more into the game.
But the pace was fast, and in this game, Bethesda had put a lot of force into aspects that would push me out of the game, like:
Providing fast travel which one would use if walking had lost it's draw because of similar landscapes and lots of fast paced, but ultimately unrewarding fights that would not let us enjoy the scenery if we could.
In Morrowind every place seamed a bit different from the previous place, you could walk around and watch a bit before the next encounter, but on the other hand, you had to be on guard and watch your surrounding with care, because you might encounter a fight that would prove too much for your health.
In oblivion all the land leveled with you, so fights would gradually lose their thrilling aspects, and also they were so numerous that would not let you enjoy the scenery, which was no big matter, because those did not change a lot, and had nothing new.
In Morrowind, you had to constantly look around to catch the probable high level item that you might find lying in a corner, and those were real treasures to find, but in Oblivion, after a few high level bandits, you would lose interest in further fights because you had all the items you needed, and those fight were always the same difficulty and would show their repeating aspects.
But those fights were relentless and face paced, so they would finally push you toward the much debated fast travel.
In morrowind you had to look around for clues to find your target cave, person or item, but in oblivion you could just follow the arrow and reach the place with no problem, so as I said before, the atmosphere was lacking, and the scenery did not change enough to warrant more focused look around after a few play-troughs, so you looked more and more into that compass which was ready for usage, and finally reached a point that you did not bother to look up much.
I do not say that Oblivion had not its moments, like dream world and the like, but those were mostly deep in the specific quests that when you played though them a few times and knew the end of the story would not draw you to them to see those places, so they were out.
But Morrowind's interesting aspects were day to day happenings like the dreamy and haunting call of those silth-striders that we could hear from a distance, or the fact that people did not like an outsider like you at first but you had to charm you way into their hearts, or those giant mushrooms that with high enough acrobatics, you could jump from one to another, like a dream, and so on...
I'm not saying that oblivion is a bad game, but you can not call that a game that you could be drawn into for long, and if you say that I have not played that, you are wrong, because I have played that for hundreds of hours trying different character to role-play, and gradually lost my interest because those problematic aspects pushed me gradually out of that world.
You know, these games are called role-playing games because we want to role-play in them, not just jump in and do some hack and slash action with quests, and feel good, and jump out.
Oblivion might have some actions and complex quests, but is not a world that would draw you in and lets you sink to the depth of the scenery and story to feel one with, and look around and enjoy the feeling, as I did in Morrowind, so don't blame us if we miss some aspect of the game that you think interesting.
