"we've always developed all our own technology. it's been a little frustrating in the past for us to hear people say, 'oh yeah, the insomniac game is running on the naughty dog engine.' people assumed that we were using naughty dog's engine for "ratchet", and that was not true. we shared some technology with naughty dog way back when, and that was great, but we are a company that puts stock in developing specialized technology and we will continue to do so." -- ted price, "independent playstation magazine", september 2006
