One of the best game experiences that I have ever had. am on level 45, I'm the master of every guild, I've beaten every quest, and i am still not tired of Oblivion. This will be a fantastic game for many more years, unless they make another Elder Scrolls game. I would recommend this game to anyone. Once you get as far into the game as i have, you can do almost anything you want. You can even go on an insane rampage killing everyone in the game without getting caught! (with the gray cowl of course)
Most fun things to do:
1. Go on a killing spree!
2. Get a whole bunch skooma, go to dive rock, drop everything, drink 8 doses of skooma, and jump off!
3. Terrorize a village with deadric artifacts
4. Make the most retarded person you can make
