A Crack in Time is ultimately what the Ratchet and Clank series has led up to. It combines everything that made Ratchet and Clank right, and adds space exploration and time solving puzzles to help improve on what was already a great formula into something even better. The music is perhaps the best its ever been, the game looks wonderful, the characters will still have you laughing, and it can even be a bit emotional. A Crack in Time is truly the defining experience for the Ratchet and Clank series.
