The Elder Scrolls 3: Bloodmoon is a fine expansion for an already excellent game; it strives to push the Morrowind gameplay system to its limits, adds new good/evil options to quests, and supplies a fully-detailed new island to run around on. While the difficulty is high, and the AI and scripting could use some work, one would be hard-pressed to find an expansion pack that adds as much as gameplay as Bloodmoon.
