Sometimes, like with critical hits, the fans wanted the game to be one way, but Gary Gygax and the folks at TSR just wouldn't have it. The case of critical hits shows that the fans have the real power, and that even if it takes decades, eventually D&D will implement critical hits, damn it.

Looks like an excellent companion to David Ewalt's Of Dice and Men.
