Star Ocean (スターオーシャン, Sutā Ōshan?) is the first of the Star Ocean video game series developed by tri-Ace and published by Enix, made for the Super Famicom. It is also the first game that was developed by tri-Ace. It was never released outside of Japan due to the closing of Enix's American division, Enix America Corporation. Star Ocean features emotional levels between characters, a real-time battle system, a Star Trekkish story, and in-battle voices.
The game was made by disenchanted developers who had just made Tales of Phantasia for Namco, and many of its features were in Tales of Phantasia as well. They left due to creative disputes, and Star Ocean features many similar ideas. The two games also stretched the power of the Super Famicom to its limits, with a total of 48 megabits of data (the most that could be stored in a cartridge). Star Ocean also used an S-DD1 chip to aid in compression of almost all graphics and map data, meaning that it effectively stored even more data than Tales of Phantasia. In the "Virtual Reality Sound System," the "Flexible Voice Driver" was again used to overcome the 64kb limit of the SPC700 chip by swapping bits of vocal samples, and a surround-sound feature was added; there were even more voices than in Tales of Phantasia (although they had to be stored at lower quality to fit within the cartridge limits).
Star Ocean was scored by Motoi Sakuraba. Yoshiharu Gotanda wrote the story that it is based on.
A PlayStation Portable enhanced remake was recently announced prior to the 2007 Square Enix Party event. It was released in the United States on October 21, and will be released in Europe on October 24.
