This should be the legal standard for any game with gatcha/loot box/battle pass microtransactions, in my opinion.
For a game to be authorized to implement random chance into its paid reward structure a la gambling, it should be required to obtain an upfront paid license, complete with a periodic regulatory spot check, and implement age restrictions that comply with local gambling laws.
That standard would be an excellent first step. Honestly I think advertising specifically targeted towards kids should be banned in general though.
They probably made more than $20 million from kids buying loot boxes without parental consent, making the fine just a cost of doing business…
Genshin has made over $3B since launch. $20M is more or less a rounding error.
