... Heck, I kinda wanna make a plural-system tabletop RPG now.
All the players share one body. :3
hypothetical plural TTRPG rambles
Every so often you roll to see if a switch happens (there's a stat for this). Switches can also be attempted by anyone at any time (including from in back). If both players (switcher-in and switcher-out) agree, or if there's an open concurrency slot, it's let's say 50/50 (although stat for that). If one of the critters doesn't want to switch, though, it's an opposing roll. Headmates have their OWN set of internal stats, changing the thresholds.
@IceWolf haven't actually played a ttrpg before but this sounds like a cool thing that could work!
@IceWolf this makes me think of the early 90's "party-blob" CRPGs where you'd control 4-6 characters that all moved simultaneously while staying in what is supposed to be a 5 or 10 foot square

Only a few players (the number is determined by your collective Concurrency stat) can interact with the outside world. Those players /should/ listen to what the other players have to say, but, RPG players being RPG players...
