Masuda: "As you know, the founder of Game Freak is Mr. [Satoshi] Tajiri, so when Mr. Tajiri talked to me about the idea he had… At that time, you could connect Game Boys with a cable, and you could play — and battle by playing in, for example, Tetris. But for this one, he had an idea of trading monsters. When I heard about that idea, I thought it was an interesting, fantastic idea. However, you then have to realize it, and make it into a game. The concept itself was very interesting, so you could expand and see how you could develop it into one game."
