Here is a game idea:
A massive multiplayer isometric strategy game where your units are your uploaded images, videos, favorite web games or website links to a public feed. When it becomes down to battels the unit’s strength is based on a hot or not EPS metric. A player earns points by raiting other player units and when it conquers more land with its own units.
Update: The player itself could be also rated by it’s webcam image in different categories so you could still choose your own scale in which you want to be rated.
Is it already implemented?
Update: Your twitter followers are your main avatars minnions!
