"give me a good idea for a game and also script it for me"

Idea: A treasure hunt game where players have to find hidden treasures on an island filled with obstacles and challenges.

To get started, you can create a script for spawning treasures at random locations on the island and a script for detecting when a player finds a treasure.

-- Server script for spawning treasures
local spawnPoints = {} -- Add Vector3 positions for spawn points on the island
local treasureTemplate = game.ServerStorage.Treasure -- Store a treasure part in ServerStorage

while true do
    local spawnPoint = spawnPoints[math.random(1, #spawnPoints)]
    local treasure = treasureTemplate:Clone()
    treasure.Parent = game.Workspace
    treasure.Position = spawnPoint
    wait(60) -- Adjust the time between spawns as needed
end

-- Script for detecting when a player finds a treasure
local part = script.Parent

local function onTreasureFound(otherPart)
    local player = game.Players:FindFirstChild(otherPart.Parent.Name)
    if player then
        player.leaderstats.Treasures.Value = player.leaderstats.Treasures.Value + 1
        part:Destroy()
    end
end

part.Touched:Connect(onTreasureFound)

You can expand this idea by adding a timer, leaderboard, and various challenges and obstacles players must overcome to find the treasures. You can also create a shop where players can spend their collected treasures on upgrades and cosmetics.
