A great, but all too short addition to Oblivion.
It changes nothing in the gameplay department, which for me is not a negative thing.
The quest is well done and adds a fair bit of lore to the Elder Scrolls universe. Although it is short, Bethesda did say it was not a full fledged expansion.
The armour and weapons added are fairly powerful, and look nice.
The PC retail box comes with all the other Betheda downloads, and that adds a few more hours of play time.
Although not a must have, its certainly a great way to spend time.
