I played a “web3” game for a while, based on real estate. It’s still around. It has some possibilities to make real-world money but seems to function mainly on game scrip, like most microtransaction games. The idea is solid, “crypto virtual property” copy of the real world, but holy cow were the developers absolutely terrible at making it fun. The non-financial mechanics of the game are the most god-awful boring thing I have ever seen. I guess they’ve improved it recently with street racing, but I haven’t tried that.
