Aren't GenY just the "elder millenials" -- the "only 90s kids understand" cohort? I did not realize they were considered a separate generation" from a colloquial standpoint.Probably a few, but I think it's still mostly Xers and Yers.
Complete tangent, although maybe not completely and totally so: why have "the powers that be" decided that generation Y needs to be forgotten and folded into either X or the Millennials? Their pop culture and generational experience is really pretty significantly different to either. I don't think that the gen x cohort who came in the early to mid 80s to D&D and had a B/X and 1e experience really had the same experience or the same expectations of the game as the gen Y cohort that came in during the 2e era. Sure, plenty of Gen Xers continued to play through the 2e era and maybe even liked an awful lot of what was happening, but the point is that they also had a completely different experience that the Gen Y cohort did not have.
But, yeah, those that discovered D&D in the 90s probably have a very different set of experiences and certainly a different flavor of nostalgia. I am a BECMI kid, the tail end of GenX. Technically I was part of the Hickman generation but since it was just me and my brothers with the Basic, Expert and Companion rules and no modules, my formative gaming years were defined by those rules: D&D campaigns are a) stuff you come up with off the top of your head, b) intended to change in style and scope over time. I discovered AD&D later and really liked it. I played 2E the longest and deepest but I still treated it like BECMI -- I never used modules and the only setting we ever played in that wasn't homebrew was Dragonlance.
Anyway, my point is that had I been a part of the "D&D community" when i discovered the game I would probably be more nostalgic for Planescape and Spelljammer than i am.
