actually, I just thought of a very simple solution for if you don’t want ectobiology in your fansession while keeping most everything else intact
instead of having the ecto babies on the meteors, and having where they landed and who they were raised by being the changed parameters Skaia has control of to determine who is a player and who isn’t
instead you can just have the sburb discs themselves being on the meteors
and your session just has people coming across the sburb discs by just happening to be near where and when a meteor lands, and getting curious enough to play this weird alien cd from space!
scratching changes where and when the actual game discs land, therefore changing which people happen to be close enough to pick one up and play it (or if it’s in the past before cd’s, they keep it as a family heirloom until some descendent realizes they can stick it in their pc)
everything works basically the same, but nobody has to make ecto children, nobody needs to be related to eachother, you can potentially have total strangers who otherwise wouldn’t have contacted eachother play together and it makes it a possibility that anyone in your universe that ever lived on your planet at some point could play sburb with you and you can scratch just the same as ecto players and do what scratching is supposed to do, which is the change the player pool for the next game
*edit* also it nicely ties the sburb disc origins into the actual game of sburb itself? Because the meteors are generated in the Medium in the first place which is Sburb Game Space? like instead of relying on coincidence, like someone on your planet happening to be the one to program sburb, the origins of sburb comes from itself, which makes sense because it’s basically a self reproducing program alongside universes itself
