The wording in the old AD&D books like the DMG are so collegiate, it helped be deal with my dyslexia when I was younger. By no means am I cured, but damn did it make a huge dent in my reading skills!
The old DMG noted the effects of drugs & alcohol, rules for gambling, and it listed some random types of Harlots. As a young man, that was awesome. Old-school characters where no Dudley Do-Rights -- when they risked life and limb to clear out a dungeon, they hit the town and lived like there was no tomorrow! Shame you don't see any of that in the newer games. The only thing it was missing was a list of recreational drugs & effects and a random list of STDs and effects. Damn, that book would improve your reading level and put hair on your chest hairs.
The old art was full of little Easter Eggs or they were based on other works of art. In the old 0-edition booklets, a teenage artist named Greg Bell made some neat, if really crude, art based on what he seen in Marvel comics (mostly from Doctor Strange, Nick Fury and Dax the Damned). (He was coping for other artists well before the comics made it a thing. LOL) Darlene Pekul did some great recreations of the woodcarvings of Gustave Doré's iconic art for the Divine Comedy, it the old DMG. Bill Willingham who is also a comic book writer and artist would add references to comic books in this D&D art. For example, he made a picture of Drows with a chest of treasure stacked with Marvel references.
In the 0-edition booklets, the Ring of Three Wishes stated that the wishes had no limit to what you can wish for. Game-balance was not a big issue then. That, and it recommends that wishes should have a literal-but-ironic twist to them akin to W. W. Jacobs' The Monkey's Paw or the Twilight Zone. So if you wish for something really game/world braking, you'll better watch what you wish for!
As for hopes...
Well, I cut myself form WotC years ago, and I have little interest in that 3.75 game, nor the up coming 5e game. I'm just sticking to the retro-clones. The OSR movement is more then what I could ever ask for. I see a lot of great works and talent coming from that great sub-culture.
