This window allows you to select the victory conditions that will apply to this game. The default is that none of these victory conditions are selected. With no items selected, the game will continue until only one player is left. When a victory condition is selected, the selector value at the right will allow you to configure the exact value for that victory condition. You can select as many victory conditions as you want to have apply to this game.

For example, if you select "First player to reach a score of", then the value selector to the right of that selection will enable. You can then select the specific score amount you want to require be reached for the game to end. If you don't change it, it defaults to a value of 50000 points required.
