Discussing Ideas for further ARGs

Hi, I wanted to discuss multiple ideas for an ARG. I'd be glad to hear you guys opinions and ideas, feel free to comment.

My idea

What do you guys think about an ARG mixing Classical 50's music, poems, and the devil as the whole context? In Minecraft, basically. The whole context goes about an entity specifically talking about a different representation of the Devil, which sounds so complex, but he picked to hunt players in the game because it's mostly played by kids, and is one of the most famous games nowadays. We can call it "Tall Man" in a way that a kid would describe it.
