I like the way they suspended sales only in Germany just to get good boy points from the German authorities.
I think it's not wrong to be pre-emptively wary of that (and prepare arguments for it), considering the way F.U.D. about "cookie banners" [1] got many people worked up against a supposedly useless and clueless law that (again, supposedly) "forces" sites to show such banners -- because their desire to track, which is the first link in this causal chain, is being ignored or assumed as given and benign.
[1] banners sites put up because they would prefer to track everyone on the first visit, rather than having an opt-in link somewhere in the footer for example.
As it turns out (or, more accurately: as people with a clue foretold from the beginning), this overestimated the willing ness of car executives to prioritise shareholder value at the expense of all else, the car industry's lobbying power, and Merkel's power in the EU.
Here, I'd similarly predict that Facebook is going to end up with most of the blame. People aren't entirely clueless, GDPR has quite a bit of support, and Facebook is only slightly above soggy bread in popularity.
But, in any case, a few thousand gamers, many of them under 18, in one country, wouldn't be able to get a law change. The EU also doesn't usually make small adjustments by passing new legislation as many other parliaments do. Instead, they do one huge thing like GDPR every decade or so (per sector).
