nahhh, lootboxes existed before CS:GO or TF2. and neither was supposed to be for kids in the first place! card games like MTG were one of the first mass created to use those mechanics
you know what was supposed to be for kids, had (& still has) lootboxes galore and other predatory monetisation tactics? Wizard101 (2008)
i don't see many people complaining about MtG or Wizard101, but folks love to point out how Gaben did a bad thing by taking something that was already a concept (that people liked) and making it digital, whereby he accidentally created something he could never uncreate
