Eurogamer writes about Planet Moon's first PSP game. It has a fascinating multiplayer idea:

"As well as a single-player mode, Infected will also take advantage of the PSP's wireless multiplayer functionality, and should put an interesting spin on things as, in addition to just blasting each other, players will be able to create a unique avatar which then spreads like a virus through the handhelds of players who lose to them. You'll then be able to check your rankings and see how far your virus has spread amongst your victims."

How cool is that? Non-Internet-based P2P game token exchanging. You could take that idea a lot further if you wanted to.
