Really? Your parents never bought you worthless junk meant to be throw away like fart putty or those rubber bubbles you blow up with a straw that barely work or packs of Pokémon cards or baseball cards?
I don’t think it should be up to the parents to tell the kids what’s valuable to them. If the kid wants a vbucks card over a game then you can tell them that’s why they didn’t get a new game.
(I do recognize that the current monetization models have ruined modern gaming which is why I only play games that are 15 years old or older)
