According to a recent chat with Videogamer.com, James Stevenson from Insomniac Games explained how the development staff has learned to perform tricks with PlayStation 3.
“After we get it off and running and we have a game or two released, three, four years into the lifecycle of consoles is where it starts to get exciting. Now we know how to ride that bicycle and we can start performing tricks on it. We had to rebuild Ratchet for PS3. All that stuff we took for granted: the move set, the animations, the character, the crates, everything that works on PS2, had to be redone for PS3.”
Stevenson dives in to much more at the link above and while Ratchet & Clank: A Crack in Time has been out for a week now in North America, it’s scheduled for release this week in Europe.
