Fast-forward to 2017, and South Park came out with its own freemium game, Phone Destroyer. Players are greeted with an opening screen informing them that the game offers in-app purchases you need real money to buy. We were going to begin that last sentence with "To its credit," but no one should get credit for announcing they're doing something shitty right before doing the shitty thing.
In the game, you can spend as much as $49.99 on a single transaction. With a tap, you can swap a significant amount of hard-earned real money for a fleeting handful of fake cash. You can then swap that fake cash for gold coins. Like every unethical game before it, it's trying to hide its cost in confusing layers of currency abstraction. Suddenly, having a fake clam-based monetary system in your game doesn't seem so stupid.
Phone Destroyer also commits one of the most egregious video game crimes: It absolutely gives players who spend real money a competitive advantage. They get access to rare, better cards to use against other players. You can earn these cards naturally in the game, assuming you make enough healthy choices to live an unusually long life. This is unlikely if imaginary South Park battle cards interest you in any way.
The entire game is a predatory addiction vampire that rewards players who spend money, which makes it easier for them to win battles and get that sweet dopamine release, which makes them want to play more, which makes them need to spend more money. If only there was someone who had an international media platform they could use to warn people against this type of thing!
