I've made an iphone version of civ. I have a full time job and other commitments so I can't really maintain or update it. The engine has pretty much all the features implemented. The world is 3D, the only part not fully implemented are 3D models.
Rather than leaving the code to die. I was wondering if anyone wanted to say port freeciv stuff to it or do something with it.
Here is the link to it in it's current state.
