When I heard some people were spotted playing a new game called Pimps at Sea on Xbox Live, my first thought was: "I must have this game so that I, too, can be a pimp at sea."
But then I read on 1up.com that "Pimps at Sea" is the oft-used moniker for different projects Bungie has worked on before they call them "Halo" or whatever.
So the smart money is on people from Microsoft playing the Alpha version of Halo 3, right now.
Boring! Who cares about Halo when you can play Pimps at Sea, dammit!
