I liked Oblivion a lot, The Shimmering Isles was a blast to play as well. Nothing like taking out tons of dungeons with an Assassin's outfit and a bow and arrows haha. The leveling up in the game is definitely easily cheated though. For instance leveling up your Sneak skill is as simply as finding where a beggar sleeps in any city, preferably by a wall, let them go to sleep and sneak towards the wall by taping your analog stick in the up direction and you get close to 10-15 levels per night. You're a Master in no time at all. But I did enjoy the game overall.
