Sony has launched an "Official License Program" to bring more peripherals to the PlayStation 3, PlayStation 2, PSP, and upcoming PSPgo.
By joining, manufacturers will "gain access to technical documentations necessary for designing and creating variety of licensed products for PlayStation platforms." Sony is working with manufacturers in Japan, Asia, North America and Europe.
At this point, I just want peripherals to work cross-platform and cross-title. I'm tired of buying new plastic instruments.
Since there isn't much more to discuss here... what is your favorite peripheral of all time? Mine is the NES Track and Field mat because you could just jump off of it and cheat.
