The problem with 5E adventures is that OSR adventures completely eclipse them in terms of quality and it isn't even really close. OSR adventure books are consistently flavorful, easy to run, easy to make your own, tell great stories, and serve as amazing toolkits. No 5E book has the usability...
I think 5E is a game designed for modular sub-systems, but has not been supported as such. There should be cinematic and streamlined rules modules for everything from ships to spelljammers to fighting on battlefields to different kinds of skill challenges to audiences with powerful beings/rulers...
This is the kind of non-typical treasure I like.
I want anything other than literal rando treasure gems and stuff. I want art with story, random but valuable monster things, magic items, manifestations of concepts, etc.
Magic items cant be cut up, are worth gold, and can be tricky to handle due to enchantments and curses. Thus, the only loot I stock dungeons with is pain in the butt magic items.
The books are literally world salad meant go inspire fantastical ideas in you. I am all for literary analysis, but the word salad is meant to justify all interpretations of a concept, not limit them.
I run every game with max HP every level. It makes the classes have a significant difference in HP, and it lets me get really aggressive with my challenges. I honestly can't imagine running the game any other way now -- it just gives me so much freedom and really has amped up tension in my games...
