first off here is what it actually says in English: https://litter.catbox.moe/nv582f71unfua3h2.pdf

These documents are actually REALLY important, surprised no ones actually talking about how insightful these are. They tell us literally how GF operates and why we're getting what we're getting

ON MASUDA AND SUGIMORI (R/B/Y era - X/Y era):
>Masuda and Sugimori were regarded as a duo within Game Freak.
>They mostly worked on Pulseman & other projects together while R/B/Y & G/S were being made, and occasionally helped on Pokemon.
>Them eventually falling out during XY was a big realisation moment for Game Freak
>They realised one person shouldn't take on all those responsibilities, it makes game dev hard
>Allowed newbies to come into management positions and the old guard being promoted.
>Hence why there's new multiple new directors (Ohmori, Unno, Iwao, Tochigi) & new people working on music like Hiromitsu Maeba (Masuda's old wheelhouse) and new people working on art like Take (Sugimori's old wheelhouse)
>They sometimes pop in to supervise (recent credits for Masuda on directing and music, plus credits for Sugimori for art prove this) but they're mostly in different roles now.

ON OHMORI (S/M era - Sw/Sh era):
>Takao Unno (BW2 director) was originally planned to be S/M's director
>Unno struggled in the role for various reasons & decided to hand the S/M director role to Ohmori
>The structural problem at Game Freak where the director had insane control over everything remained in place during this period
>They did nothing to fix the core issue
