I guess i disagree with the majority here. I think aside from a strange auto-leveling implementation for enemies that Oblivion is a great game with a good amount of depth..
But I guess I can just post my review..

Oblivion. Oblivion. Oblivion. So aptly named and so desperately addictive.
Bethesda Softworks and 2K games have delivered the finest title yet for Microsoft's new Xbox 360. Those who plumb the world of Oblivion for action and adventure will find themselves losing touch with friends, forgetting to eat and possibly foregoing the other big game releases of the next few months.
Fourth in the Elder Scrolls series, Oblivion tells the tale of the Imperial capital of Cyrodiil. The emperor Tiber Septum, pursued by demonic assassins, spurs you on a quest to find his bastard son.
The loss of the emperor and his heirs means the lands of Tamriel are susceptible to invasion by the demon princes many worship as dark gods. Restoration of the bloodline of kings will ensure the safety of the world, but it's a long and arduous journey from the prison cell you start in to the final confrontation.
Don't want to save the world? Frankly Oblivion doesn't mind. Players can craft their own experience in this vibrant setting. The game doesn't force you along a main storyline.
The design is carried over from the previous games in the series but never before has this world felt so realistic. The computer-controlled characters all live their own lives, with likes and dislikes and even daily routines. Don't expect the traditional static shopkeepers—these folks have things to do other than propel your silly game.
Oblivion is easily one the most gorgeous Xbox 360 games, but on a high-end PC it looks even better. This beauty comes at a price, however, since most home PCs will require serious hardware upgrades to run the game smoothly at anything more than minimum detail.
Gameplay is the king here. Players can choose any number of careers and actions. Simply walking through the world reveals hidden caverns and dark ruins filled with unique encounters. The question of replay value is moot since Bethesda offers official add-ons at a moderate charge through Xbox Live! or via the Internet.
Oblivion isn't perfect. Aside from the steep hardware requirements there are a few poorly implemented systems that players will find frustrating.
Wise players will find it easier to bribe characters to raise their attitude rather than mess with the game's odd influence system. Rogues and thieves will discover the utility of unlock spells quickly since the lock-pick mini-games are hard to manually execute on both the PC and the 360.
Oblivion is easy to recommend to anyone. The joy of exploration, the epic quest and the amazing environments all make this a must-have title for the 360 and, dare I say it, an instant classic for the PC.
