... the Jak games always beat us every year. Jak 1 did not sell very well, and then they made the change, and than Jak II and Jak 3 sold better than Ratchet 2 and Ratchet 3. Not by a ton, but they did outsell us. And so, we had all done three Ratchet games at that point, we were all ready to try something different, so we thought we'd try something different on the story front also, which is one of the reasons why it's not named Ratchet & Clank: Something About Butts.
Ratchet: Deadlocked (or Gladiator in the UK), changing the way the title was structured, changing the format, making Clank an NPC – like all of those things were, we wanted to try something different, because we'd spent four years trying to make Ratchet 3, and in the process we made Ratchet 2 and Ratchet 1, right? So a lot of us had been doing it for a long time, so we just really wanted to try something different. It wasn't really that we thought it would sell better. It was just that we thought, you know, this had a good response from gamers when Jak did it, so maybe we could do something similar.
We didn't really want to make it dark - you know? Like that's not very Ratchet & Clank. We just wanted it to be a serious story with high stakes.
