You can bet your asses this is not the end of this. Hawaii also announced to take actions and I’m failry certain it won’t be the last. Here is the video of the announcement. It just needed a big scandal so that goverments are FORCED to react. It will start with a few here and there, until the majority will have certain restrictions in place. I’m fairly concerned what might be conidered problematic, this could affect other, fairer, microtransaction systems too (Warframe, Dota, Lol, Guild Wars 2).
To help with the region lock debate. Its easy and its done already everywhere. No Germany has no special tools to prevent you from buying black market titles elsewhere, but its strictly forbidden to do so. If you are catched selling to Germans, or owning specific banned games you will be in the shit. This can range from money fees to jail time.
In general it USED to be easy to get around it. Now they are trying more to prevent the sale itself with tougher sanctions. Not sure how well that works but I’m a bit out of the loop, my informations are around 8 years old . Still it seems your Steam account uses some of the informations where it was created. I was forced to buy the key for Wolfenstein (3 years ago) somewhere else, as Steam was insisting I have a German steam account even while living in Japan! That in itself wasn’t as easy anymore as it used to be, lots of restrictions on people buying games outside the region, only a few shops are willing to deal with that.
At that time Steam was using IP certification for ACTIVATING the key, easily circumvented by VPNs. But in recent time some developers use the certification not only for the activation but also while running the game or even for downloading it. That makes it borderline impractical to play games outside your region, for a couple of reasons.
VPNs bandwitdths aren’t too great (I have a paid one) and have trouble with peer-to-peer connection types. This will result in higher pings which you can deal with if you won’t play competetive. The problem is downloading the game, you can’t download 40+ GB with a VPN that bugs out every now and then. Best example I know of is Black Desert. Since they updated to that system I can’t play it anymore as the download crashes all the time while using a VPN, caused by the larger package loss. There are methods to detect VPNs too, popular example would be the one Netlix uses.
All in all, the technology for region lock is already widely used and effective, you just don’t know about it as you barely come in contact with it.
