I'm interested in playing Ratchet and clank tools of destruction, do i need to play the others first? - ratchet and sasha

As the title. I have never really a game Ratchet & Clank, made before, but it struck me. I need to understand to play their predecessors, which is new or can I just pick up this game and I should be.
