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!
