You know, the one that comes with the artbook? Is it worth the money? I don't really need the strategy guide itself, but I'm looking for Xmas presents for myself. I'll probably ask for Kohler's book, but in the interest of not spending too much, I'm trying to determine whether I want HL2: Raising the Bar or the MGS3 artbook/strategy guide. Right now I'm leaning towards the former, but if the latter is good enough, it might be worth it.
