Cuthbert explains his level of involvement on the original StarFox

“Myself and Giles were the two main programmers. We worked on location at Nintendo the entire time. The whole game was our domain and we worked very closely with Miyamoto, Eguchi and everyone else. A lot of the ideas came from us; the storyline and characters were totally Nintendo’s doing of course, but I did come up with the names for Fox McCloud, Slippy and Peppy. Falco was thought up by character designer Takaya Imamura.” - Dylan Cuthbert
