Joined Square with Sakaguchi in 1983 and was a programmer on Sakaguchi's first two games, The Death Trap and its sequel. Took charge of his own team and made several games prior to rejoining Sakaguchi later in FFI's development. Stayed on as chief game designer through FFIII. Transitioned from the early stages of FFIV while it was still planned for Famicom to SaGa 2 on GameBoy, then seized the opportunity to take charge of Seiken Densetsu 2 (which he turned into a million-selling real-time RPG on SFC). Directed Seiken 3 himself, but it failed to sell 1 million. Then he produced (and designed the game systems) for Xenogears and Chrono Cross. Too bad he had to leave Square last summer.
FFXI was like a Tanaka (producer) and Ishii (director) reunion from the Seiken 2-3 days, plus Kato (Chrono, etc.) in charge of plot and event supervision. When FFXIV was first announced, it was exciting because Tanaka was back as producer, Komoto was director (he was FFXI's original event director and man in charge of Bastok and related events. He also worked on select scenes in Xenogears (incl. the Thames), the ATE scenes from FFIX, etc.) of Chains of Promathia when Ishii left the team to pursue his failed attempt to revive Seiken Densetsu (which he had originated on GB, if you don't count the original trademark Square had for the FDS game by Kazuhiko Aoki), Yaeko Sato replaced Kato (who left to go freelance) at Chains of Promathia (it had been planned from the beginning, but Sato and the others decided how it would be implemented). Etc. Etc.
Anyway... there's little point to this. I just saw the question re. Tanaka and felt, as a longtime fan of Tanaka, I would comment. Sakaguchi and Tanaka were like this awesome one-two punch (like Joe Sakic and Peter Forsberg were for the Colorado Avalanche) back in the nineties when their names were attached to games like FFIV-VI, CT, FFVII and FFIX and Seiken 2-3, Xenogears and Chrono Cross, respectively.
Wow! Apparently Naoki Yoshida was a map designer on Super Bomberman! I remember buying Super Bomberman on SNES with the Super Multitap with four controller ports. He worked his way up to director in the Bomberman series before leaving HudsonSoft for Square Enix, apparently. Then he directed numerous Dragon Quest spinoffs prior to serving as lead game designer on DQX. If DQX is any good as a MMORPG, then FFXIV can't be much worse off given it's generally considered more flexible than DQ as a series.
