[gaming][EU][from late March, I've been busy ok] So the EU is cracking down on premium game currencies. Games in the EU will now have to 1) let people buy the exact amount of currency needed for an item they want and 2) offer refunds for both items and premium currencies.
Companies shouldn't mix multiple currencies when someone is paying for something (ie, this costs blue prisms and white prisms is considered a way to obfuscate the true price of something.)
Consumers have the right to return items/currency within 14 days in accordance with EU law. (the actual phrasing is "withdraw from the contract" which makes sense since you're typically licensing a product, not buying something.)
The instructions for companies also say that if gaming companies are going after vulnerable populations, like children or 'whales' (yes, they use the term) those companies will be under stricter scrutiny.
Whales are considered a vulnerable population because, the EU says, in the nicest way possible, they at best have poor impulse control and at worst are gambling addicts.
Oh and any game that is not explicitly and exclusively marketed to people who are legal adults will be assumed to have a contingent of players who are children.
They don't give explicit instructions on what parental controls should be in use, but I assume there's an expectation that buying items and currency are gated behind parental controls by default.
