This game is rather boring, and the story is nothing to write home about. I normally enjoy Salvatore's writings, but this game does not live up to his books.
Also, this is categorized as an RPG. If you buy this game, expecting an RPG, you will quickly realize that this game is not one. Yes, it is set in a 'RPG World', and it uses classes/items/spells/skills from an RPG game, but the similarities ends there. This is a pure action-based, completely linear, Hack'n'Slash game, with no real RPG elements whatever.
If you love those types of games, maybe you'll like this one, but for me, who love games like Baldur's Gate and Neverwinter Nights, this is a huge disappointment and was really not worth my time.
