Loading a Game
AT THE START OF A GAME
In the Main Menu, click on “Single Player,” then on “Load Game,” it will take you to the Load Game screen.
Click on the “Game Menu” button on the upper-right of the main game screen (or press ESC), then click on “Load Game.”
The program automatically saves the game every turn. (You can alter the frequency of these auto-saves in the Options screen ) To load an auto-save, bring up the Load Game screen, click on the “Auto-Save” button, then on the auto-saved game you want to play, and then click “Load Game.” The auto-saved game will load, and you’ll resume play at the point of the auto- save.
Another save/load option is available to you: “Quick Save,” which is especially useful when you’re in a hurry. Press F5 to “Quick Save” your game. The game is then saved without requiring any further input from you. Only one game can be quick-saved: any future quicksaves will overwrite the current one.
