Hideo Kojima is INFP

Yong: So you're telling me that Kojima wanting to make the game the best it can be is what started the conflict?

Daley: Yes. In her eyes, Kojima's a fantastic creator, and probably the best creator of his time, but he doesn't have a strong business sense like Konami would like him to have. Where instead of, for example, cutting corners by lowering foliage resolution, he wants to make sure everything looks as good and polished as possible. She said they paid for her to write 30-40 songs that ended up not being used, and he'd tell her to write another one, then another one, then another one, because he settles for what he likes and has a good mind for what people want to see and what people want to hear.

Weak Te is what caused the rift.

Despite the coffee cup example above, Kojima seems to have an eye for detail:

What games have inspired you recently?

Kojima said that while he was playing GTAV for a few hours, he noticed all the small details and felt full of envy because of this. This happens for all the games he really likes.

So while I can see ISFJ, ENFP, and ISFP as possibilities, I can't imagine Kojima as a dom Ti or Ni user.

Actually, I'm really starting to think Kojima is ISFJ:

"[They] are very difficult to understand. They are overwhelmed by impressions and need time to assimilate them. [They] are often preoccupied with images from the [depths of the psyche]. Even [their] precise observation of reality does not stop [their] subjective factor from working." - Frieda Fordham, 1953
