After years of online underage gambling (and several truck loads of money) the ESRB has finally decided weigh in on the matter: You're getting a tiny warning symbol on packaging that uses a passive euphemism designed to normalize the concept of microtransactions until they sound like the jump button on a control pad.
This helpful symbol will be amended to your mobile device's app store, since everything
with an option for an in-app purchase is included such as DLC, so you won't actually know which ones offer a premium service such as ad-free and which ones use literal gambling to drain your account dry within minutes. However even the most obvious layman will know it costs money to use it without having to be techsavvy.
And of course this new tag can be used to restrict young children from even opening the game, kids love that, but not actually prevent them from buying stuff once opened unless you change open a second option and set their allowance to $0. Provided this is even an option on the gaming platform(s) you, your spouses, and your children use. These settings are disabled by default and buried within various menus because if you're dumb enough to need an icon on the box you're too f**king stupid to find them or even know that you have to turn them on anyway.
Here is a better idea, take all that money EA paid you and refund EA's customers. The euphemism you're looking for here is "lawsuit".
