I think it's somewhat interesting that the first two editions of AD&D fairly accurately map to developments in rock music - the height of 1st edition's popularity coincided with the zenith of metal, whereas 2nd edition came into its own just as grunge was taking over the music scene. Whereas people from my friend's older brother's gaming group were all into Iron Maiden and Slayer, if you passed the room where our group played all you were likely to hear were the raw sounds of Mudhoney, Dinosaur Jr., Screaming Trees or Soundgarden. (Never Pearl Jam, though. It was our highly developed and well informed opinion that they were shit.)
I sometimes wonder if that had some sort of influence on "the game" itself. 1st edition AD&D is, as a general rule, a pretty gonzo and simultaneously hard-edged affair, which always seemed to me to reflect "metal" rather well, whereas 2nd edition tends towards a slightly (although only very slightly) more "grungy" introspective and emotive feel. Obviously the comparison is hardly perfect - 2nd edition took a deliberately unironic and heroic view of fantasy, which is pretty much the opposite of the grunge mentality - but I think there's a case to be made that it had a more slightly more reflective and arch approach (although 2nd edition was all about high fantasy, it seemed to have a far less hard-core view of what good and evil represented; just compare 2nd edition Baatezu and Tanar'ri with devils and demons from 1st). And all the grunge bands were much more reflective and arch than their 1980s metal forebears.
Or maybe I'm overthinking it.
