The bottom line with the game is this: if you liked Morrowind and want more of the same, Bloodmoon will be perfect for you. It's more or less exactly like Morrowind, which I suppose is to be expected from an expansion. If you feel you were more or less done with Morrowind and have no real desire to keep playing in the same vein, you should probably look elsewhere. This expansion doesn't offer much besides more places to explore, more quests to complete, and more monsters to fight. Good for some people, not so good for others. You decide which category you fall into.
