Loot boxes have arguably been the biggest controversy in gaming this year, especially with regards to the boxes in Star Wars: Battlefront II. It seems that Apple has taken note of the backlash, as it's implemented more stringent regulations on loot box systems.

Apple updated its App Store requirements recently, adding a clause that forces developers to disclose loot box odds. Now, games with random rewards available for purchase must tell players the chances of getting each type of item in a loot box.
