It's a simplified version of games like Civilization. It has some similarities to Catan (I actually first thought of the idea in college, early '90's before Catan was around).
It is different enough from both of these games to have it's own niche. Everything is on the board, there are no cards or money. Basically you build developments (for resources) urban centers, and a movable pieces called "influence pieces" which are of three types: cultural, political, and force.
Like catan, the board is built early in the game by the game players.
That's the basic idea. Of course, the play of the game is the important thing, and I used spreasheets and math equations to help me balance the dynamics out. So I'm thinking it should play pretty well.
