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.
I would like to know more about how it would play, concepts or something.
Good questions. I don't know, but I have ideas, as I'm sure others do. Fundamentals have to be established:
* Persistence
* Instantiated content (yes, no, hybrid phasing)
* NXT or another coin
Do we go for a game playable on a cheap mobile or something that harnesses SLI, AMD 7750, etc. Can we/should we have both?
I like the appeal of a light client that encourages leveling, customizing, crafting, collectibility and community. A social RPG that could earn NXT and is user driven.
At any given time, half of a WoW server is sitting inside of Goldshire cracking Chuck Norris jokes.
EDIT: James -- Panda is offering 1000, and I'm tossing in another 800. Which account do we send this to?
