My Take

As someone who values craftsmanship in games, I have enormous respect for Koji Igarashi. Joining Konami in 1990 and rising from programmer to creative director, he helped define the sprawling, exploration-driven style that shaped a whole subgenre, work that earned him a spot on IGN's list of the top 100 game creators of all time. What I admire most is his consistency: a willingness to perfect one vision rather than chase trends. His later move to independence, building new projects hand in hand with fans, shows a creator who trusts his audience. IGA, to me, embodies the patient, world-building discipline that leaves a lasting mark on players.
