Save Game Button
If you want to save a game in progress, click on the Save Game button. A dialog box will pop up, asking you to name your game. Type in a name and click OK and your game will be saved. (You will not exit the game after saving.) This dialog box also allows you to remove previously saved games. Just select the name of the game you want to remove, then click on Remove.
If you are playing a network game, only one person in the match needs to save the game, though more than one person may save the game if desired. Information on all players will be saved. When the game is resumed, anyone who has saved the game may act as the Host for the resumed game.
