Yes these things do occur. People want to validate and re-experience in a new way something they believe in and love. Christianity is to Judaism as 2ed ed. AD&D is to 1st ed. AD&D. (A slight twist on an already well founded base.) As is Zoroastrianism, is to Judaism, so to, is OD&D is to 1st ed. AD&D. (A basic foundation upon which many new rules and concepts were derived from.)
I hope the above does not offend anyone as I am not comparing the merits of the religions themselves but only using them as a metaphor that I am familiar with.
Things change even in our own campaigns and game mechanics, so that even if you don’t buy in to all this hype; there would still be a flux of changes (improvements/updates) in our games. Not only is it human nature, but it’s the 2ed Law of Thermodynamics.
I want the definitive/best game as well. Even though I know this can never exist.
Point in case- By the time I got around to watching The Battle for the Planet of the Apes, I got to see it Widescreen, Digitally Mastered THX and Dolby Digital sound, Digitally Re-mastered footage, Extended Edition with 10 min. more never before seen footage, tons of behind the scenes footage, Spanish and French as well as Captions (should I need any of these last for friends) on a Dual Layered Digital Video Disk that I can see again and again with no reduction in sound or video quality. Not bad for a 1973 film. I think I got my money’s worth.
