A fun little tidbit of info: The Legend of Zelda: Ocarina of Time took 40-50 internal Nintendo employees to develop, and more than double that figure when you account for external contractors.
“Forty of fifty. It’s the biggest development group I’ve ever had. We also have a programming company working closely with us. If I include those people, maybe 120 people are working on Zelda altogether.” - Shigeru Miyamoto, Nintendo Power vol. 111, 199818 years later, The Legend of Zelda: Breath of the Wild's development team was over twice as large as Ocarina’s. The core team consisted of over 100 staff, while the full list of people working on the game amounts to over 300.
