I am not going to give Ken much credit for "facing" Nintendo, it seemed to get personal with him and that was a reason for releasing the PS1. Like I said, he was probably a good engineer, but I think praising him for anything beyond that is a stretch, he was a guy that was promoted to a position he wasn't cut out for, but because of certain things aligning during that period he was able to ride on a wave of success. Now if Nintendo would have ditched, and lightened up on 3rd parties things WOULD have been different (Losing Square most likely would have never happened, and they have been key to Sony's sucess). Perhaps I am wrong, but wasn't PS2 considered to be a pain in the butt to program for? Developers get around programming difficulties, and I don't see that as a big issue, at least not on the level of Nintendo screwing publishers or keeping carts.
P.S. Am I the only one that thinks it is sad that Ken's greatest innovation for the gaming industry was a good sound chip?
