Minecraft, Roblox, Fortnite, MMOs, Second Life, there's heaps of sandbox games where people can just hang out and do their own thing. It's the metaverse that Facebook / zucc just completely misunderstood.
They could've just bought any one of these titles and they'd have a better metaverse than whatever it was they pumped billions into.
Pokopia and Tomodatchi only look like sandboxes at first glance. They are far more directed. They're not a perfect square with you in the middle. They're a star shape with you in the middle.
