I came across Farsite a few days ago. Yes, I know...where have I been the last few months. Trust me, I wish I came across Farsite earlier.
In case you are like me, and you don't know what I am talking about - Farsite is a block-chain powered sandbox MMO RTS game with elements of adventure in a sci-fi setting based on a post-apocalyptic story. It is also positioned as a persistent virtual universe with player-owned and player-controlled economy running in a trustless environment.
If you want to see what it looks like, have a look at this: https://farsite.club/u/redpig-travelling-the-universe
Although Farsite has been around for a while, it appears to still be in the early stages of development, so it is a great time to get involved. I hope to explore Farsite over the coming weeks, and will report back on my progress.
