Dear Scotty,
Civilization III is already a great game and will stay forever a great game. I think it is balanced because when we talk about game balance we talk about units, city improvements, wonders. The only thing I would change in this game is the combat system because I don't like seeing my tank losing to rifleman or swordsman
. The AI is something else, you cannot balance it. Maybe you can program a better AI but it will never beat a human being under the same conditions. Comparing chess with Civilization is a mistake. For example, there are 64 squares on a chessboard and in Civilization on a standard map there are thousands of it. In chess, the squares in the middle are the better for your pieces (there are 4 of them), in Civilization you have many terrain types that can be good or worse depending on many other factors. Chess has not change since it was created whereas Civilization always evolve a little bit when another game of the series arrives on the market. Finally, chess programs are very strong these days but they still have many holes to fill. You often see a top player like Kasparov or Kramnik beating the crap out of it in a closed game. Chess programs also benefit a lot from openings in chess (a pure sequence of moves that you can learn easily by memorizing it) because if you would make it play Fischer Random Chess and always mix the start of the pieces it would get crush game after game. In Civilization, the pieces are always mix at the start of the game and you have now 31 sets of pieces in the Conquests expansion whereas chess has only 2 sets of pieces and they are the same except that White has the initiative at the start at the game.
