ES4: Shivering Isles - Review @ AtomicGamer

The latest Shivering Isles review comes from AtomicGamer, who awarded a score of 89%:

 But it's the interesting designs that went into both the world and its characters that really make this expansion so endearing.  From Sheogorath's constantly amusing dialogue to the larger degree of emotion and mood that goes into the world design and its inhabitants, I think you'll find that while Oblivion was more of a traditional RPG setting, this expansion channels a bit of that alien weirdness from Morrowind and then takes it to a new level with the Mania/Dementia angle.
