I get your point with Decentraland, but the dynamic data is all on the Ethereum network, the static data is all on IPFS, and anyone can run a node and have their own instance of the world for them and their friends to play on. Sure, they have some hard coded authority for which NFTs get included in their marketplace, but people are free to switch that up on their own instances. Sure, there are ways in which it could…
Can I bring up a Decentraland server and sell my own land?
All land sales happen on chain, so you can do it all directly from Etherscan if you want, no need to spin up a server.
Also, yeah, it's all open source. You deploy your own world contract, and point your version of the Decentraland engine at your contract, and you're good to go. You now control all the land and can sell it off as you see fit. You can even have a small property in the primary Decentraland which teleports you to AnimatsLand, and you could let people wear their same NFT outfits and everything.
