Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "victoryconditions.txt" file in the "\space empires v\data" directory. You will see a text document with the Victory Conditions. Look at the top line of it and it end with: the game is over. Change the words: "is over" into: "continuos". Now save the changes and start the game. If you complete your mission(s) it should now say that you can now continue playing.
