If you need advice or help on the missions, don't be afraid to ask. There are a few favorite levels in the game despite its challenges for me
P.S. - There are minor spoiler comments below. Just highlight the text.
If I recall correctly, R.A. Salvatore contributes to the Drizz't Do'Urden part of the story. There's good decent voice acting with Patrick Stewart and Michael Clark Duncan playing important roles. I'm sure you'll come away with a favorite character and mission yourself.
