My daughter informs me that over the past two days kids on TikTok have made a completely player-generated, decentralized game where people buy things with "doubloons."
Video pop up where someone (sometimes a poorly animated cat) gives you doubloons, steals doubloons, or tells you what you can buy with your doubloons.
People keep track of their doubloons in the notes app on their phone, or if they're even more hardcore, they run a google docs spreadsheet to keep track of all of their money flowing in and out from various transactions and thefts.
Everyone is on the honor system to keep track of their money and goods correctly. It's getting very complex. My daughter reports that doubloon inflation has become a major issue, because anyone can add more doubloons whenever they want by simply making a video.
Apparently you can buy all sorts of goods and services, including insurance that pays you back when doubloons get stolen!
All sorts of strange behavior and etiquette questions come up. My daughter says she can usually tell right away if a video is going to be a "thief" saying they're stealing from you. So she quickly scrolls past, avoiding the theft.
I asked if she's allowed to do that, but she said she didn't know, because everyone is just making up how to play it at the same time.
