A few weeks ago a US lawmaker named Chris Lee called out loot boxes as a form of gambling and made specific references to Star Wars Battlefront II. It looks like instead of trying to get loot boxes banned altogether Chris Lee is pushing for games with the loot box mechanism to only be sold to people over the age of 21.
This would only apply to the US but if the law does come to pass you can bet other countries will follow. Lee is also pushing for developers that have loot boxes to reveal loot box drop rates odds so that there is more clarity on the chances of unlocking a certain item.
Very interesting times indeed for games that have loot boxes but only time will tell if laws such as the above actually come to pass. Once again I think this would only apply to loot boxes with non-cosmetic upgrades that have items with game-changing effects.
