"We wildly underestimated how difficult the transition would be from the bright and cheerful PlayStation 2 graphics of the Sly Cooper games to the gritty and realistic PlayStation 3 look of Infamous. In effect, we tried to take two steps at once. First, we needed to catch up with the realism in the best-looking PlayStation 2 games; second, we needed to match the even higher quality bar being set by the best teams as they moved to the next generation of hardware.
"This was a struggle on multiple levels. First, we had a technology gap to clear; the engine we used for the Sly Cooper games needed to be substantially rewritten to run on the PlayStation 3. We needed to rework our whole pipeline to accommodate things like vertex and pixel shaders. Unfortunately, we didnt start this effort until after we completed Sly 3, leaving us without a pipeline or engine running on the target hardware for the first 10 months of product development.
