It's certainly been fun to build. Right now I'm working on a character creation and PVP aspect. You can see the latest test for the PVP aspect here: https://steemit.com/ibt/@lordnigel/welcome-to-the-ibt-development-zone-player-vs-player-adv-test-game-on-steemit
I've never made a game before so it has been challenging, but lots of Steemians are helping.
Once the mechanics are good I need help making it look nice. I have a friend helping, but its proving to be a real challenge.
Cheers
