The Elder Scrolls: Oblivion is just too big

So, as probably none of you know, I am currently playing through the Elder Scrolls IV: Oblivion on 360 for the first time. While my views on the game change day by day, I can safely say that the game is just too big, and too long for the average consumer. Thus far, I have put over 40 hours of my free time into the game, and I expect that I am about halfway through. In this day and age, I am aware that many people are calling various game developers out for creating games that are too short -- 8 hour spectacles that barely live up to the hype that they are given. However, I am calling for the opposite. For the average person, Oblivion is just too massive a game to enjoy. Sure, I loved the game for the first day and a half of gameplay time that I committed to it. However, dungeon crawling and quest-fulfilling is starting to get old ... incredibly fast. My experience with Bethesda-created games is very limited (only played Fallout 3 for a couple of hours before losing interest), but I believe that developers need to focus on creating plot-focused games that deliver more on story-line and action and create less drag than the games that we are now accustomed to.
