- players working together to pull off successful combinations of their unique skills thru switches.
- players bickering over each other's bad habits, the ways they are "always doing this with our body ugh, you know I have to live here too!!"
- moments of delightful teamwork among a tight knit family
- moments of delightful ineptitude among a group of people with resources spread just a little too thin
im not really a ttrpg designer, in fact we are WAY TOO adhd to even scrape together the spoons to PLAY them ourselves, let alone develop one. so if someone hears this and goes "oh holy shit i wanna make that", be my guest! do it!! free idea!! i probably wont do anything with this myself, im too busy with other stuff!! also if you think of a better name you should probably call it that.
the original conception of this, as infodumped into a dm excitedly at our friend, was that there would be some kind of corru observer style weird sci fi internet of shared thoughtspace, minds connected together as well as to computer systems, called the Inside, and it would be like a lasers and feelings hack where the Inside score of a headmate means better at solving problems thru thoughtspace hacking, "on the Inside", and Outside means better at solving problems thru physspace action or social engineering, "on the Outside". perhaps combine that with tokens, possibly aquired thru no dice no masters style "weak moves" that can be spent by a headmate to switch in.
but again, not a designer. maybe a l&f hack would not be the best option for my desires for lighthearted plural sci-fi shenanigans, or maybe just in general! i think no dice no masters might also be a really good fit for this concept.
honestly i think you could take the concept of a ttrpg where all the players share the same body in a LOT of different directions, to both less lighthearted/more serious places, to fantastical places, to weird and experimental places, to fun places and dark places, to slice of life places. (and we'd be honestly surprised if it HASNT been done before by some cool indie ttrpg artist)
but personally i just REALLY want to argue with my friends in our headspace over how we should best use our body to get out of a sticky situation while some clueless singlet is just standing there watching our body just stand blankly for slightly too long
but doesn't mechanically differentiate between players. everyone just acts similarly – the same AI, just at different times
this would make that combat system more fun, though!
it's even canon-compliant! (AIs can form gestalts, though this is usually for fleet coordination / (grand) strategy funtimes)
