You might like to check out @steem.craft http://steemcraft.com which is something that I came across recently. I haven't played on their server, so I cannot recommend it at all yet, but I see that they apparently reward $SBD for killing mobs (not PvP) in the game. It sounds intriguing.

I play a bit of Minecraft, although mostly on my Xbox 360 console, so I don't really play online much. I created my avatar and profile wallpaper images in Minecraft.
