There's no reason to see why a 10-year-old girl or a 51-year-old girl wouldn't like a Ratchet and Clank game. Ratchet and Clank connects different universes, meaning you're going to span the planets gathering bolts to buy new weapons and armor. Depending on which game you play, some you may prefer more than others. Each one has a different storyline, and some have different playstyles. Ratchet and Clank: All 4 One is a complete cooperative experience, the first, whereas Ratchet and Clank Future: Tools of Destruction is more akin to the older ones, yet bears witness to high-definition glory (the first of its kind).
