Nintendo banned Square from their offices for 10 years after FFVII went to PlayStation. EDIT: japanese business model is akin to Yakuza

Yamauchi was a hard-arse to a fault.

His ruthless approach to business led Nintendo to dominate the 3rd gen and overpower the Megadrive in the 4th, but it also meant he was unwilling to compromise, and effectively told third parties to go fuck themselves in the 5th gen.

Iwata was more tactful by contrast.
