thanks for dropping this question, its a fun one to think about, I'm not sure about Q&A so right place for asks about, but... let's see what we can discuss about )) As I know microsoft actually doesn't own the minecraft story mode ip.
Telltale games developed it, and after their shutdown, the rights got messy. netflix even had temporary streaming rights for some episodes! wild, right?
Microsoft's main focus now is on minecraft itself and spin-offs like dungeons or legends. but hey, u got a point, if they could sort out the licensing, re-releasing those seasons would make fans super happy (and yeah, probably bring in some cash too).
if u're looking for something similar, check out minecraft legends. its got that story-driven vibe, just in a different style. and who knows, maybe if enough people ask, microsoft might push for a revival ))
as for other platforms, its always worth keeping an eye on digital stores like gog or steam. sometimes old games pop up there when rights get untangled. also, physical copies of mcsm still float around secondhand, just check ebay or local game shops.
wish i had better news, but hopefully this clears things up...
rgds,
Alex
