How can I make my game not start until there are a certain number of players in the server?

I wanted to have the game I made not start until there are at the very least 2 players in the game. I have tried:

game:GetService("Players").PlayerAdded:Connect(function()
	if (#game:GetService("Players"):GetPlayers() >= 2) then
		-- Start the game
	else
		-- Tell the player that there needs to be at least 2 players to start
	end
end)

The thing I am worried about is that if there are 2 players in the game and another player joins, the game would start from the beginning again. How would I modify the script in order to start the game when there are at least 2 players and will not start again if more join?

EDIT:

I have decided to use a boolean saved in a variable called debounce. This way when there are 2 players the game can start and if more join, the game will not restart again.

debounce = true

game:GetService("Players").PlayerAdded:Connect(function()
	if (#game:GetService("Players"):GetPlayers() >= 2 and debounce) then
		debounce = false
		-- Start the game
	else
		debounce = true
		-- Tell the player that there needs to be at least 2 players to start
	end
end)

If there are other solutions, please let me know!
