I feel a strong positive emotional response when I look at comics and books and TV shows and the like from when I was a kid in the 70s, and from the pop music of the 80s. I don't feel that way for the old roleplaying games, strangely, perhaps because the real pleasure was in the playing, not the reading. Well, maybe for RuneQuest 2nd edition and Gamma World, but otoh those games are just plain good, aren't they? I don't feel anything like that looking at old D&D books, except for the Erol Otus art (but I don't think that's nostalgia, I like his new stuff just as much). For me the 1e DMG is just a historical artefact.
My first rpg experience was playing Basic D&D and I freaking *loved* it. (I was 12 years old.) But I feel zero nostalgia for the game. It's kind of weird, that.
