Is Ratchet & Clank: a quest for booty easy to platinum?

Unfortunately, there are no trophies in Ratchet & Clank: Quest for Booty. It was just a small mini game that takes place after Clank was taken away by the mysterious Zoni in Tools of Destruction. Quest for Booty was just a filler for Insomniac Games, so they could devote more time to A Crack in Time. It was their plan to bring out a new game each year, but their newest game All 4 One, has not been able to meet that deadline. There is no difference in QfB and ToD, the exception being you don't travel through the galaxy, and you lose all your weapons at the start of the game, so you have to go and find them. Your Companion on this mini adventure is Talwyn who is just support in fights, like in ToD.
