It might have a chance. If even 100 game owners in France all complain to the regulator, they might investigate and issue a large fine? idk how realistic that is, but it’s plausible. Conservatively, if 100K copies sold in France at 50€ a pop (?) that’s 5 million €. That might be sufficient precedent to keep other companies from deleting millions of users purchases regularly. It wouldn’t cost $5MM to build offline play capability into games, especially if it’s designed for it to begin with.
I’m Canadian; I’ll do my part once the petition goes live here, but I doubt Canadian regulators will do shit.
