On the physical side, popular products used in this way include baseball cards, Pokemon, Magic the Gathering, and Labubu. In the game space, digital packs similar to our boxes date back to 2004 and are in widespread use.
I think that video game loot boxes are very much different when you're hiring psychologist to maximize fomo and extra currency to make kids spend more with 100 gems short of your next purchase.
But if they want we can outlaw baseball cards and Pokemon too. I'm good with that.
