Nintendo, Sony and Microsoft are developing new policies to require games to disclose loot box odds on Xbox One, PS4 and Switch. Loot boxes are common in games such as Overwatch, Call of Duty, Middle-earth: Shadow of War and NBA 2k18. Originally developed for monetizing free-to-play mobile games, they are virtual tools that can be bought in the digital world. Full implementation of this feature is expected in 2020. Some loot box items are cosmetic with no influence on gaming success; however, others are designed to induce players who spend money to succeed. Example: The 2017 game Star-Wars Battlefront II has been criticized for loot boxes requiring full retail prices while not providing the items as expected. Previous industry efforts to limit loot box problems included ratings and password-protected spending controls. The new loot box odds will be presented in a clear and understandable way according to the Entertainment Software Association.
