Game forge released a game about a month back on the same concept, but if you do what your saying in this game I am sure it can surpass that game also.
This game of yours sounds fantastic and fun to play.
Just a few questions:
1) Will there be a military and war aspect to the game
2) Will there be a clan/guild system
3) You say that your looking for people to help you improve the game, is this payed work or just suggestions
4) Can you please translate the game link you have provided
5) You say you have a 3D artist with you, so is this a 3D game or a browser based rpg like torn.com or something
Thats all for now ;)
