How do you make your game/server automatically shutdown by itself?

I've seen games where servers automatically shutdown by themselves after you completed a game.

I want to know how it automatically shuts down by itself after a choice dialog is finished.

It would be helpful in many of my games to know this.

[edit]

Here is how to detect if a player has selected a dialog choice.

local BadDialogChoice = --Insert the FULL name of the dialog choice like workspace.Part.Dialog.DialogChoice1
BadDialogChoice.DialogChoiceSelected:connect(function(plr)
	game.Players:FindFirstChild(plr.Name):Kick()
end
