Although this isn't Miyamoto related, I want to share a Miyamoto inspiration on how Sega was created

Yuji Naka was inspired by the Mario games series created by Miyamoto himself to make Sonic The Hedgehog in 1991 when designing the classic gameplay for the gaming companies, Sega, Sonic Team, & M2. Provided with the mascot itself to compete with Nintendo's Mario games. I think the Sonic series is my favorite because I grew up with it, along with Mario, since my childhood, and up to this day, I've never forgotten these childhood memories and continue to cherish memories like this from time to time.
