Gamefront: After having spent many years playing and replaying the Ratchet and Clank series on Playstation 2 and Playstation 3, we were extremely excited when Ratchet and Clank: All-4-One was announced. We were also extremely curious since it turns out All 4 One was to be a coop platformer with elements similar to New Super Mario Bros. Wii instead of a proper installment in the series. Would a significant change from previous games in the series work? Yesterday, we attended a Sony event in Los Angeles hosted by Insomniac games, and got the chance to spend a goodly amount of time playing 3 levels from the game. The long and short? Yes, it works, and with some caveats, we loved it.
