WASHINGTON (AP) — Parents whose kids bought virtual gear without their knowledge on the popular Fortnite video game could soon be able to get a refund.

U.S. regulators are starting to notify more than 37 million people by email that they may be eligible for compensation as part of a legal settlement with Fortnite’s maker, Epic Games Inc.

The Federal Trade Commission announced late last year that Epic Games would pay $520 million in penalties and refunds to settle complaints revolving around children’s privacy and its payment methods that tricked players into making unintended purchases.
