i'd really love if they tried to really extrapolate how other species cultures would logically differ from human society stemming from their own biological traits, similar to that, oh i forget what it's called but there was a thought experiment setting that tried to look at how a world would actually develop if things like teleportation circles and plant growth all those other magics that logically should have a massive impact on society did have the impact they should. (edit found it, it was the tippyverse)
like for elves who only need to trance for 4 hours a day, maybe that might create a whole 24 hour society where everything is open all the time and instead of having dedicated bedrooms there are little bubble room motels that you check in for 4-hours at a time that are treated more like public benches, and the idea of shutting everything down for nearly half of the day so people can sleep is insanely inefficient to them, how does your entire species being resistant to charm effects influence their society
maybe dwarves with darkvision, tremmorsense and an innate constant knowledge of just how far underground they are, resulting in pitch black cities where the only light is from the fires of the smelting forges, where colour is a near alien concept to them as is logically inked writing, but record things in texture and sound
or halflings, what would be the results of a species having nigh-supernatural luck and they know it
I actually really like this line of thinking. A few have noticed that I'm thinking in a more sci-fi way than a fantasy way when thinking about species, and that's true. For my own setting, I know each of the species evolutionary origins (humans are apes, halflings are spider monkeys, dwarves are badgers...) and have been thinking about how to truly differentiate them from humans.
Elves having a 24 hour day makes a lot of sense. They can see in the dark, so moonlight is fine. They like the outdoors and are adapted to their environment, so sitting on a park bench and taking a 4 hour trance isn't out of the question. Their charm resistance may make it so they don't legislate enchantment magic like other species might.
Being that dwarves often live underground and rely upon their darkvision, maybe dwarves don't write and paint because darkvision lacks color. Instead, they carve statues and chisel for writing; it's just easier to see in black and white. Their poison resistance could lead to not just strong alcohol, but frequent ingestion of poisonous plants and animals, seeing poison as a spice or a base flavor.
Halflings' innate luck and resistance to fear could lead to some really reckless behavior.
As for humans having wanderlust, do we really? What's the percentage of people who haven't left the area they were born in? Certainly there are adventurous humans who travel and explore, and maybe we have a higher percentage compared to other species, but there are migratory species to compare to. An avian species that migrates yearly might have way more wanderlust.
I do also like the lizardfolk emotion description, of where they perceive their emotions as sensations rather than feelings. It's interesting.
And I do love the idea of "the creator deity of humans is dead and Asmodeus stole its portfolio". Humans having The Devil as our patron deity makes for some good cautionary tales.
