''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 ''VideoGame/ValkyrieProfile'' series. Creator/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).
