GameSpy questions Ted Price, the man behind Ratchet & Clank about its Sequel, Ratchet & Clank: Going Commando and various other bits:
"GameSpy: What do you think the main improvements are in Ratchet & Clank: Going Commando?
Ted Price: I think that ... as far as improvements go ... improvements imply that what I'm talking about was in Ratchet 1, so I'll say that technology, we definitely improved the technology. We have improved the effects in the game. We have completely revamped a number of systems, which I'd say is much more than improving them. We've revamped the way enemies work, their behavior. We've revamped the way that enemies ramp up as far as their hit points and damages go. We didn't even have a ramp in the first game. We certainly completely changed the way that Ratchet progresses in the game. There wasn't really any character progression in the last game. This time there is."
