Here is the key info:
The Gaming Commission now judges that this is at least three video games in violation of the gambling legislation. 'An interview with the sector is imminent. It is often children who come into contact with such systems and we can not allow that, 'says Minister of Justice Geens.
In the case of FIFA 18, Overwatch and Counter Strike: Global Offensive, the Gaming Commission considers that the system of loot boxes is a game of chance that is subject to Belgian gaming law
The games with paid loot boxes, as currently offered in our country, are therefore in violation of the gaming legislation and can be dealt with under criminal law. The loot boxes must therefore also be removed. If that does not happen, the operators risk a prison sentence of up to five years and a fine of up to 800,000 euros. When minors are involved, those punishments can be doubled.
There is a bit more there, but this is the key info.
