I love the NWN series! but this expansion has a huge let down. As part of the story you become a spirit-eater and have to feed on spirits constantly to avoid negative effects and eventually death. The main problem with this is that in MOTB resting and travelling take certain amounts of time. Say resting may take 8 hours and when you wake your spirit meter is either dangerously low or you are simply dead. Problem? going a spell caster class is nearly impossible! I played as a spell caster for about halfway through the game and had to quit and start as a melee character because i couldnt rest to replenish my spells. Melee is just boring but this game kinda forces your hand and limits your possiblilities.
The story was actually really good but the gameplay was so torturous and i had to force myself to play it just so i could finish the game. Its taken me a little over a year to finish the game but there was roughly 10 hours of gameplay… not so good.
