This may be a bit late to mention, but at the time R&C came out for the PS2 I always felt that despite it being a native 60fps game, it never felt as snappy as J&D that came out more or less at the same time and was perhaps the most similar in style and gameplay. Someone that wants to play a snappy-oh-god-this-is-how-a-platformer-should-feel-like should play J&D (the first one). No idea of course how SO will play, given it's 30fps, but it's something that I felt all Insomniac platformer games suffered a bit. No idea why, maybe design choice... never really thought too much about it at the time and just loved the games for what they were - brilliant entertainment and a very solid platformer.
