Like, it could be a 2-D map, simple pictures, if any. Just make a game that would incorporate all the gameplay of CIV5. I have a feeling the Civ community could design a game as well as Firaxis.
Then if it gained enough popularity, perhaps it would be taken over by a company that could produce the game with good graphics also.
