I've been digging deeper into the Decentraland project. I think this team can really make this grand vision happen. (They are leagues ahead of some of the other "VR on the blockchain" projects out there -- which shall remain nameless -- that only have a white paper and a website, and no experience in this industry).
Decentraland has struck up important partnerships with other respected blockchain projects too. For example:
District0x to support the sale and resale of Land in the Decentraland world: https://blog.district0x.io/decentraland-districts-40b9ada0431b
Aragon to enable decentralized governance within the Decentraland world: https://aragon.one/
This article does a great job of explaining these partnerships and the overall plan for MANA tokens and LAND in Decentraland: https://vrscout.com/news/decentraland-metaverse-blockchain/#
With the token sale coming up on August 17th, this is one to watch.
Here's an article they posed about how to participate: https://blog.decentraland.org/how-to-participate-in-the-decentraland-token-sale-1833cf0b8137
