Damn, a game would be cool. Maybe I could help? I have some ideas 
Panda, we need your voice and as many as we can possibly manage. Gamer's know the challenges of balance, and ultimately, what's FUN.
And for the Nxt ecosystem, game mechanics that will ding the pleasure/reward center of the brain to encourage LOTS of transactions.
There's http://nxtopia.wordpress.com, and I also reserved nxtopia@gmail.com and @nxtopia. I'm not beholden to the name, even as a working development title. But if we agree to use it (even short- to mid-term), I can register nxtopia.com.
And I decided to put 10% of my account balance (800 NXT) in with James' 5000 NXT bounty. I started playing the first D&D supplement in 1976 (age 7!) and haven't been the same since. Bringing this to fruition is beyond anything I could've hoped for as a 7 year old dice hoarder.
