ES4: Shivering Isles - Review @ GWN

Describing it as possibly the "perfect expansion", Gameworld Network has reviewed Shivering Isles with a score of 96%:

Expansions for popular PC (and now, with downloads available on next generation systems, console) games are certainly nothing new, but rarely are they anywhere near as exciting as the original release.  In most cases they simply add additional content or a few new missions; allowing for a certain degree of replayability or the opportunity to simply make the core game last a bit longer.  The Elder Scrolls IV: Shivering Isles, the first full blown expansion to Bethesda's impressive Oblivion, does something more.  This expansion does more than simply add to the experience provided by the core game; it improves upon it considerably.
