I just finished it last night, well finished the main quest and the other faction quests. I made almost the same character that I had in Obliviion (a Khajiit archer/thief/assassin and played most of the game on expert dificulty.
In Oblivion, I made god tier armor and weapons. Maybe I missed it somewhere, but even with both Smithing and Enchanting maxed out my gear was nowhere near what I could previously make.
After spending over 200 hours on the game I decided to just finish it up. I was expecting the final boss to be a bad ass cat eating machine. The sad part you ask? The bastard went down in five arrows, not even making use of a lot of the equipment I had created.
I was expecting it's corpse to raise from the ground for some epic fight, but nothing ever happened.
All in all though, I haven't had this level of enjoyment from a game in a long, long, LONG time. Half of the glitches I ran into weren't game breaking, they were just funny. Random bandits, giants, and all other sorts of beasts just plummeting form the sky. (I'm thinking they pissed off a dragon somewhere
)
One of the Dark Brotherhood quests I was following my mark waiting for him to find an inn or some other place where I could off him in his sleep. I followed him for three days in game time, just then an Ancient Dragon picked up my target and flew away. I never did find his corpse and I had to load a previous save.
Now, on to a new character...
