A large house with 15 streamers. They all compete for the most growth within a specific time frame (say 3-6 months), but they are allowed to prank each other, without physical harm to others or hardware, in means of sabotaging others so they can grow more. The top 3 highest growth streamers make it on to the next "season". It would create a lot of competition and drama, and having streamers do it, means that they would be posting constantly, updating their audiences.
