Examiner writes "I had the opportunity this week to play and see a demo of Ratchet and Clank: All 4 One in downtown LA, and the game thus far is a whole lot of fun. And by "lot," I mean cooperative, 4-player gameplay that incites some entertaining competition and an imperative to work together to succeed and progress. We were ushered into a room with five Sony HDTVs, each with Ratchet and Clank: All 4 One hooked up to each television, 4 controllers to each, and battery-powered stereoscopic glasses on some of the setups. Oh, yes. The game will be available in "eye-popping" stereoscopic 3D when it debuts."
