Nomura wrote the whole script this time while going hikikomori and living on canned food for two weeks
"-- In this game, did you write much of the scenario yourself?
Nomura: I arranged the main parts of the scenario, and referencing the plot that Kanemaki-san had put together, I wrote everything from start to finish. For two weeks I didn't see anyone, lived on canned food, and wrote the whole time. After I finished writing I had Kanemaki-san go over the dialogue, had Ishida adjust and correct the fine details, then made the final revisions myself.
-- Is it unusual for you to write even the dialogue yourself?
Nomura: This was the first time I'd done it. In previous titles, I'd write the foundations of the plot, but apart from points where I wanted characters to say particular things along the way, I didn't put in the dialogue. So rather than what we call the scenario, it was really just the plot, but this time I thought, "Why don't I try to write this myself." And as you might expect, it was tiresome. When I finished writing, I said "I never want to do this again." (laughs)"
