Ratchet and Clank

There has been a large influx of gaming in my house.  The thing is that It's my girlfriend that has been doing all of it lately.  She's hooked on ratchet and clank and most of the time won't even let me play.  She's bought all of the PS2 Ratchet and Clank game used so far and finished all of them but Deadlocked and Size Matters.  She told me she won't beat Deadlocked, and she is currently working on finishing Size Matters.
