It's basically digital Lego where you have to work/Mine resources and there 's some monsters etc. It's a sandbox game and uniquely able to be altered with plugins etc.. Mostly I wanted to integrate Bitcoin Lightning in a way never done in a game before and learn and expose my kids to Bitcoin in a fun way. You can see a video on Sovereigncraft.com to see the ways Lightning is integrated if curious.
NIP-05 was just a fun little add because it's cool to have alias registration with verified in-game character names
