Gacha games and kids. Keep them away? Or expose them to teach?

I have a 7 year old and more and more often we find a mini game that she enjoys either on phone or switch, that very quickly goes from fun to "game over. try again for 1.99?"There's 2-3 off brand pokemon games on switch store (a cafe and blocky/pixely game) that were free to play. I saw as demos, so care free let her try them. But after seeing her so upset over missing out on a '1 day only' event, I looked into the game and they were blatant gacha games, hoping their parents enabled the 'remember password' on the device.I recovered from a mobile addiction a while back, so know their destructive power on your finances and family very well. But I'm torn on how to approach this with my kid.What we discussed.-These are called Gacha Games. They are designed to upset you. They start super fun, then after you play them long enough, they get so hard that they frustrate you. Then they try and convince you to skip the hard parts by 'spending a bit of money' but that can end up lots of money with each level you play.So now I'm torn between two option.!: Let her play them to teach her what are the signs of a gacha game, and learn how to enjoy the free2play side. Hopefully to end with her knowing what to watch out for.2: Teach her of gacha games and the signs, but don't allow her to play them. I'm not up to date with gambling habits, but wouldn't want to be inadvertently training her to be an addict years later.Anyone have advice? via /r/Parenting https://ift.tt/3xaoV7V
