Gamers of a certain age will remember the Official Nintendo Seal of Quality. It was a little mark placed on official Nintendo products in the NES/SNES era (well, that’s when it mattered) that let buyers know that, yes, this product has been blessed by Nintendo. It will not harm you, your cat or your NES. Fast-forward several years and now Sony has gotten into the business of slapping their logo on officially licensed gear with the “Official Licensed Product” gimmick.
In exchange for a big sack of money, Sony will give peripheral developers “access to technical documentations necessary for designing and creating variety of licensed products for PlayStation platforms.”
