Fun Facts

Did you know these bits of trivia?

Some of the staffers made appearences in the game. Most were removed from the English localization, but Gamer Miki can be found in Sopia town.

Naoto Ohshima handled visual design for Odin because Rieko Kodama felt she couldn't draw such a musclar man. The original Sonic the Hedgehog was also designed by Naoto Ohshima.

Uwabo Takehiko handled music for most Master System games, not just Phantasy Star.

Rieko Kodama's pen name was Phoehix Rie in the game, but a popular misconception often has it spelled as Phoenix Rie.

Yuji Naka went on to be involved with many other Phantasy Star installments, including Phantasy Star Online and Phantasy Star Universe.
