1. Ratchet and Clank 3 Up Your Arsenal 2. Ratchet: Deadlocked/Gladiator 3. Ratchet and Clank 2 Going Commando 4. Ratchet and Clank ( First one ) 5. SSX 3 GO R&C!!! Also, go snowboarding games! Anyway, these are my choices ^^ Also, I choose these because people think it's hard to beat because of the crowd of powerfull enemies that are actually easy-ish to beat ^^ and Gamespot also loves these games, they gave 'em awesome reveiws!
