Bernie Stolar is the guy you're thinking of. As the first president of SCEA he implemented a "no RPG" policy in the early days of the Playstation because most at the time were 2D, which he felt didn't showcased the PS1's power. Therefore it's logical to infer he discouraged any games from being 2D during his time there. He was released from Sony after the first holiday season of the PLaystation and then went over to Sega, where he oversaw the Saturn and the time leading up to the Dreamcast launch, before being let go from there also.
