I’m aware that exists. But the experience of an MMO on a community server must be pretty different (but I don’t know).
If the desire is to not lose the experience after the company shutters the project, I’m not really sure that’s possible. Maybe it is for WoW. But I can certainly imagine a game like Pokemon Go or something being developed by an indie dev that works by orchestrating live real-time events depending on players locations. Would this game even be allowed in the EU following this law? They can’t allow users personal locations to be released, they can’t create a game they can’t eventually fully release to the public. Even if they found a way to strip out users locations, the experience would be completely broken. So what’s the answer? Just don’t innovate in that space?
