"The coolest thing is the four person death match, via WiFi (as shown in the 2nd video). A few weeks ago, Diego, Mike, Martin and I spent a long time in a dark room playing Halo. That was fun, but it was sort of an effort to get us all in the right place with the right equipment to play. It'd be sooo much cooler to be able to start up a match completely ad-hoc: 'Hey, we're having a barbecue this weekend, don't forget your PSP!' :-)"
