In the Team Fortress lore, Shakespearacles, the strongest writer to ever live, invented rocket jumping. A few centuries later, Abraham Lincoln invented stairs. He died while rocket jumping up them.

It's well known that ancient dwarves enjoyed the practise of banging rocks together through the shins of the elves. One day, the rocks sparked against each other and set the elf ablaze, and that is how dwarves discovered fire. They loved fire, and used it to set many, many elves ablaze.

From that day, it took 30 years to invent cooking.

Dwarfish folding chairs are studded with gemstones and weigh about 500lbs.

They’re a very inventive people, but refuse to work with sheet metal.

Elves build lightweight folding chairs out of wood.

In my setting I dropped darkvision for dwarves because I wanted to make it scarce, but even the dwarves that don't study light or dancing lights use their many lighting inventions that were developed for underground exploration such as flairs and glow sticks, and gas lighting for their main settlements.

I also gave them all spiderclimb just because I like the way that fucks up how they'd build those settlements as down is only a necessary direction to know when you drop something, even their tankards work at all orientations and are basically sippy cups.

Halflings definitely invented egg timers

My setting has technology more-or-less equivalent to Earth's 17th century, and a big chunk of my inspiration is Neal Stephenson's Baroque Cycle. The books detail the steps that led to the industrial revolution so my setting also has similar early tech, aided by magic of course.

(Airships, for example, use magic derived from Resilient Sphere to make their balloons supernaturally rigid and impermeable, then instead of filling it with a lifting gas they just evacuate all air from it. Their hulls look like solid wood but they are instead a honeycomb structure made of giant spider silk sandwiched between thin wooden veneers to keep the cold air out, and reinforced with the occasional mithral spar. The propulsion is purely magic though, the props are powered by aetherosiphon engines. There are some secret military projects aimed at creating a fully-pressurized heavier-than-air skyship that can actually fly over the taller mountain ranges; since their passenger compartment is not pressurized, a standard skyship's maximal cruising altitude is 3-3.5 kilometers while a trained military crew can maybe get up to 4.5 km.)

Yeah, that sounds pretty on-brand!

Elves invented wooden folding chairs and then the dwarves made them from metal for better weapon usage.

I am currently reading Cryptomancer, a game with crystals to do kind of Internet things.

Hmm…a certain author has elves running a car racing team, but that’s not an rpg.

I can just picture it now. A dwarven hell in a cell style match. Someone gets knocked back into an open chair in classic comedic WWE style and the whole crowd goes quiet. All you can hear is the collective thunk of thousands of chairs suddenly opening.
