It boggles me that people are so profoundly interested in continuing on their own "personal experience" with a game to the point of barring the enjoyment of even an alternate telling of the same story in another format, by the very same creative people that made the game experience so enjoyable.
I think it must be some sort of narcissism-by-proxy effect with their game Avatars, or something else along those lines. In any case, it's kind of disturbing - think of it this way, there is such an intense association/identification with a game Avatar (or Character in general, because I believe this cross into other media as well), that any other alternate interpretation of this character is not only "not interesting", but to some people, down right abhorrent. It's like the identification is so strong that reinterpretation isn't just a curiosity, but a down right assault on their own self.
I don't know what to say here other than just maybe there might be a little bit too much "escapism" going on in some people's lives (Ironic I know, given the web site name here...). I admit that I have known some people who have gone through phases like this, and it's often been accompanied by deep depression and it's very worrisome how these two things go hand in hand (and how prevalent they are in people who enjoy sci-fi/fantasy genres).
