The problem with it is, from my point of view, that it is a story that requires a certain (huge) degree of do-it-yourself retconning. A lot of the things written are exaggerated far beyond necessity in the hopes of enforcing a sense of scale that could be better attained elsewhere. A lot of items are just silly, and need to be swept under the rug. The story is a mess, and is therefore one that works best if you rewrite it using the existing text as guidelines. The story isn't great. After all, it's the setup for a game. It's an interactive story. It has to be made great through its coexistence with gameplay, tabletop or otherwise.
