Naughty Dog's first foray into the collect-a-thon 3D platformer model, popularized by Super Mario 64, and then perfected by Bubsy 3D, proved to be a worthwhile venture because the end product is an iconic action platformer with an impressive technical edge that's only sometimes betrayed by its abhorrent camera and occasional input lag making some double jumps and dive attacks miss (or maybe I just suck, but not nearly as bad as the game's camera)
