How to use math.random in a way to get a name out of a folder?

This is actually pretty simple. All you would have to do is get the children of the folder and then set up math.random to select an entry of the table :GetChildren returns. For my example, my folder will have 5 entries.

local gameFolder = game:GetService("ReplicatedStorage").gameFolder
local games = gameFolder:GetChildren()

local function chooseGame()
	local num = math.random(1,5)
	local chosenGame = games[num]

	return chosenGame.Name
end

local nextGame = chooseGame()

print(nextGame)
