If you're not familiar with the Neos project, it is (from the Steam page):
> Neos VR is a metaverse engineered for the unknown! It’s one of the most versatile and feature rich metaverses for virtual reality, designed so everybody can find something interesting or useful to do in a social setting.
> It serves as a casual hangout experience with multimedia and games, creator, builder and developer sandbox, professional work tool, educational experience and much more!

Disclaimer: I'm not a dev of Neos, just a big fan of the ideas behind a "metaverse," as I'm sure many of you here are also.
