I don't see why everyone has to vote 10 all the time, even if they don't claim the game is perfect. I frankly don't think this expansion deserves a 1 but it's obviously not 10 either. So here is my vote for a little balanced.
Almost a full-fledged sequel in its own right. Not only do you get the full original game, but you also get a new campaign with a more than respectable amount of game time, new spells, treasures, monsters, and improved interface options.
Legends of Aranna delivers. With about fifteen hours of gameplay, lots of new items to collect, and a horde of monsters and boxes to destroy, this expansion offers plenty for gamers who love to increase stats and find fancy weapons and armor. [Jan 2004, p.155]
