I might be really biased here... and I'm frankly speaking out my own ass when I say this...
But I really find it hard to like or enjoy any game-based novels. Every time I go into my favorite book shop I see a whole shelf of books titles something like "Diablo 2 : blah blah", "Warcraft -blah blah blah"...
I just don't see how that can be good. I really distrust this sort of thing. And this will probably offend some of you out there, it really seems that most of this type of novels are just mass produced to get more of the fanbase money. The few books I touched, I didn't like.
Don't remember the title, I think it was something by Knaak... or whoever made that horrible "Ronin" character.
