Is it fair to criticise a sequel because it offers nothing new? After all, there would be no sequels if there wasn't demand for more of the same. Having ordered a meat feast pizza, do you complain because what turns up is just like the last one you had? Maybe you just wanted another meat feast pizza. Except with the pepperoni, ham and smingy brown stuff arranged in a slightly different order.
Ratchet & Clank fans who just want more of the same won't be disappointed with A Crack in Time. It's pretty, polished, funny, expansive, satisfying and rewarding, just like all the previous instalments in the series. There are hordes of enemies to batter and bolts to collect. There are puzzles to solve, doors to open, rails to grind on and jump pads to bounce off. Despite the global economic meltdown, business at the crate factory must be booming as there are endless piles of boxes to smash open - wooden ones, metal ones, exploding ones, more wooden ones.
There is a new plot, of course. Clank has been kidnapped by the Zoni at the behest of the evil Dr Nefarious, and Ratchet is on a mission to rescue him. Along the way he bumps into a grizzled old fellow Lombax, General Azimuth, and they join forces. Captain Qwark returns to provide comic relief, and there are plenty of good, occasionally Hitchhikers-esque jokes right from the start (opening voiceover: "Space. It's huge. So huge in fact that if you lost your car keys in it, they would be almost impossible to find.")
