Shivering Isles is the official expansion pack to Elder Scrolls IV: Oblivion. Along with entirely new quests to complete, main quests and side quests, it comes with new items, and an entire new area of play. This expansion adds about an extra ten to twenty hours of gameplay, depending on how much you immerse yourself in this new world. The gameplay is essentially the same as Oblivion, but the land is new and different. You will not be able to rely on anything in Cyrodiil, unless you're willing to brave the tediously annoying loading screens to go between the two. So, you may as well just bring along everything you need with you when you enter the gate. In the Shivering Isles, it's important to take note of a few things. There are not any houses to buy, so there is no storage directly available to you after entering. Also, the Lord of the land decided that he hates horses, so you're going to have to run everywhere. The graphics are essentially the same, but the landscape of the differing parts of Shivering Isles is truly amazing. The entire land is divided into two parts, Mania and Dementia. Mania being a more artistic and colorful side, while Dementia is essentially the opposite. The audio received an upgrade. There are several new tracks that have been added to the music, and new sound effects. A few new voice actors, but much of them remained the same. The controls remain the same as in the original game. Also, the game comes with more achievements! Which is a bonus, for all of you who like to complete those. This is a must have for all die-hard Elder Scrolls fans, and a nice way to spend your time for a casual gamer. Dark Blade gives this expansion an A-.
