Everybody, who has even played any of the Geneforges, knows the basic idea, how the Shapers rule and the serviles are slaves, who go rogue and fight back and youre caught in the middle of it. Honestly speaking, this idea has been chewed up over and over agan making it really boring. Only the graphics and sounds, maybe even the map differ from the last one, but the idea is still the same. Each game has to be unique. Like the first Exile you made was unique, then you began to make a whole lot of Exiles, which were basically the same by the storyline and didnt have the punch anymore to offer any good gaming experience, since you would know how its gonna end. You need a NEW idea and a storyline! Let the next game you will make, for an example be - by the view of a servant, who has to follow his masters, but his masters get killed and you go rogue and venture off into wildness to live through unbelievable adventures.
Or maybe make a game, where magic and technology co-exist, like in the game "Arcanum: Of Steamworks And Magick Obscura" (those of you who have played it, know what im speaking of). There are many, many ideas how to bring life into your games, invent another storyline, or something else. You really should consider making a new game with a whole another viewing aspect.

Edit: And btw, the type of the game Geneforge marked in the Our Games page is NOT 3D, the background is totally 2D, you cant spin your view, which is one great minus. Only the living creatures can turn their backs on you. If you need an example, then C&C Renegade is 3D, by my experience, Geneforge is definetly not.
