Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Hideo Kojima's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.
A structural wave is external to the person, even when their position improved access to it.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Hideo Kojima's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Born in Setagaya, Tokyo; father Kingo was a pharmacist who traveled for business; family moved to Osaka when Kojima was 4. Parents were passionate about cinema and instilled a nightly film-watching tradition. Father died when Kojima was around 13.
Father was a pharmacist; parents were passionate about cinema, exposing Kojima to films from a young age, which influenced his cinematic game design.
Kojima grew up in a cinema-passionate household in Tokyo and Osaka, with a nightly film-watching tradition that shaped his cinematic approach to games. His father, a pharmacist, died when Kojima was 13, forcing him to abandon art school aspirations for a more practical university path. He joined Konami in 1986 and directed Metal Gear in 1987 at age 24, creating the foundational stealth game genre. His deep film and literature knowledge, rare among game designers of the era, was his key differentiator.
