“His achievements remain in the minds of the fans”
Though Martin helped mold the image of Sonic in his own right for the West, the interview is with one of Sonic’s original fathers, the man who molded his original image–Naoto Ohshima.
Said Ohshima on Martin’s legacy:

….I think his achievements remain in the minds of the fans.
