Use Roblox studio, it's basically a game engine to develop games for Roblox, uses Lua and has a marketplace full of things like 3D models, it's best to start with a simple platformer, Roblox has tutorials on their site. Before that if it's too much, they could make things like shirts to wear in game and sell those to other players, easiest is to use a template and something akin to photoshop. Roblox is closer to a game marketplace where the games are made by fans than a game unto itself, so the creativity isn't game inherent unless it's subgame was built to be like that (most aren't).
