when you set the settings in beginning of game the computer picks the number of Ai players, very seldom will it max out the number of players, also I don't pick neutrals because they don't do much, I turn neutral off, but if you want all 20, then go to I believe its add empire and pick all the empires you want to play just remember that one has to be human controlled (you) you can also edit their racial traits this way, the only difference you would know which races start the game, only not where they are.

just some ideas mac
