The Entertainment Software Association has said that Sony, Microsoft, and Nintendo will adopt new policies in the coming year that will require a loot box odds disclosure on their platforms.

The announcement came during an FTC workshop examining Consumer Issues Related to Loot Boxes.

"Microsoft, Nintendo, and Sony have indicated to the ESA a commitment to new platform policies with respect to the use of paid loot boxes in games that are developed for their platform," said ESA's senior policy counsel Michael Warnecke.

"Specifically, this would apply to new games and game updates that add loot box features, and it would require the disclosure of the relative rarity or probabilities of obtaining randomized virtual items in games available on their platforms."

Following this, the ESA released a statement confirming the three publishers and console manufacturers "will require paid loot boxes in games developed for their platforms to disclose information on the relative rarity or probability of obtaining randomised virtual items."

In addition to this, a number of publishers have also agreed to the disclosure – including Activision Blizzard, Bandai Namco, Bethesda, Bungie, Electronic Arts, Take-Two, Ubisoft, Warner Bros, and Wizards of the Coast. This will come into effect "no later than the end of 2020."
