Petition: Require videogame publishers to keep games they have sold in a working state
petition.parliament.uk
Require publishers to leave videogames (and related game assets / features) they have sold to customers in a reasonably working state when support ends, so that no further intervention whatsoever is necessary for the game to function, as a statutory consumer right.

If this gets 100,000 signatures, it will be discussed in parliament. We have half a year, so this is doable! Sorry for indulging in so much electoralism lately, but this really does feel achievable.
