If it presents itself as an Action-RPG in the open world, the miHoYo game is nevertheless closer to gacha. For this reason Genshin Impact may be blocked in some countries, those with laws against gambling in video games. The game just doesn't show up on the PS Store. However, the game remains accessible on PC and mobile.
Belgium suffers from this problem in particular., not having the possibility to download it, or even to find the game. In the list of available countries shared by miHoYO, Belgium is supposed to be able to enjoy the game. However, this is not the case, Genshin Impact still being stuck in the country because of its business model. For the moment, no official solution has been shared for this problem. Given the law, and what Blizzard did to circumvent the problem, miHoYo could correct this injustice by the next update, by simply blocking the store for the countries concerned.
While Belgian law is particularly strict with regard to gambling, China is just as strict, if not more so. Nevertheless the game is not blocked in its country of origin. This is not because it is considered a national treasure, but only because the law prohibits this kind of practice if the rates are not publicly disclosed. Genshin Impact therefore avoids this sentence by having shared the exact details of the Vows. This slight distinction could therefore end up being adopted in other countries.
