Belgium's gambling authority, the Belgian Gaming Commission, has launched an investigation into Star Wars: Battlefront II and Overwatch to determine if the loot boxes in those games constitute gambling, according to VTM News. Games of chance require a permit from the Gaming Commission in Belgium, and due to the random nature of loot boxes, they could fall into that category.

Belgian Gaming Commission director Peter Naessens said (via PCGamesN), "If there is a game of chance, it is not possible without a permit from the Gaming Commission." If the commission determines that the loot crate system is a game of chance, the publishers of the games in question--Electronic Arts and Blizzard--could have to a pay a fine amounting to "hundreds of thousands of Euros." It's also reportedly possible that the games could be removed from sale in Belgium.
