The major difference of a Kinder Surprise, is that there is no gaming or other experience connected to them. I'm still not a fan, but buying Kinder Surprises doesn't give you any type of advantage in a corresponding game. This is not the case with Pokemon cards, so at the very least those should have warning labels and odds listed. Loot boxes are potentially worse on many levels because they're usually purchased with virtual currency which are designed to distance consumers from real world costs, and lock their funds on a platform. Also depending on the design of the game system, they can give whales an unfair advantage making a game pay to win. Finally, and perhaps most important, is the experience of opening the loot box, which obviously use all of the psychological tricks to get your attention and trigger all those neurological responses that addicts are vulnerable to. The flashing lights, bright colors, vibrant animations, exciting sounds all add up to trigger that response in the brain just the way a slot machine does. They may not be able to classify them as gambling, but they are manipulative, should be accessible only by adults, and should be regulated.
