A Chinese Animal Crossing New Horizons player has monetized Nintendo’s latest installment in the series by basically creating his own in-game currency.

While New Horizons currently doesn’t feature micro transactions or in-game purchases, the Chinese player has set up his own real-world economy by allowing other players to buy custom-designed in-game items. As posted by industry analyst Daniel Ahmad, this particular player has set up store on its own island with custom designs and has added AliPay and WeChat Pay QR codes as a custom design which allows players to purchase the items with real money.
