Apparently even the Minister of Justice in Belgium agrees with my opinion, as they’re looking to ban all games with gambling aspects defined as “any purchase made where it’s not clear upfront what you will receive”
And it’s not like Europe is the first to do it, as China, South Korea and Japan already has certain laws in place (see gatcha games and such).
This is from the Dutch site, one specific thing the Gambling Commission noted:
NL: “Het vermengen van geld en verslaving, is gokken”
EN: “The mixture of money and addiction, is in essence gambling.”
