Live service games could make tools so players can set up their own servers and keep them playable (for example, I think FiveM could keep GTAV multiplayer going even after GTAO closes their servers), but single player games are the bare minimum.
And even if you can't sign, it would be nice if you shared it in other Europe/gaming focused communities (in or outside Lemmy)
Well, the deadline is getting closer and there are only 40% of the signs...
