“among the preliminary sketches I drew, one of them looked like a dinosaur, and Kojima did single that one out. "Let's go with this."”
— Yoji Shinkawa
Shinkawa recounted in 2001 that when he was assigned the mecha design for Metal Gear Solid he worked locked in his house with almost no orders from above, the main instruction being just to make a very cool-looking robot; among his preliminary sketches one resembled a dinosaur, and Kojima singled that one out and decided to go with it, producing the design of Metal Gear REX.
“There were almost zero orders from above [...] the main thing I was told was just to make a very cool-looking robot.”
