''tri-Ace'' is a video game development studio. The studio was founded in 1995 by Yoshiharu Gotanda, Joe Asanuma and Masaki Norimoto, all formerly of Creator/TelenetJapan's Wolf Team (which at the time had been developing ''VideoGame/TalesOfPhantasia''). They are now best known for the ''VideoGame/StarOcean'' and ''ValkyrieProfile'' series. MotoiSakuraba (who had also been associated with Wolf Team) is almost always the music composer for their works, and almost all of their games (which mostly consist of {{Action RPG}}s) have been published by Creator/SquareEnix (Enix pre-merger).
