Codex Gamicus

tri-Ace, Incorporated (株式会社トライエース Kabushiki Gaisha Toraiēsu?) is a Japanese video game development company formed in 1995 by former Telenet Japan employees Yoshiharu Gotanda (programmer, current tri-Ace President), Masaki Norimoto (game designer) and Joe Asanuma (director). The name is a play on words regarding the "three aces" who formed the company. All but one of tri-Ace's games have been published by Square Enix (originally by Enix).

The group exclusively makes console RPGs, and is known for giving their games action-packed battle systems and deep skill systems. This trademark style began when the founders of tri-Ace originally worked for Telenet Japan's Wolfteam, and had created Tales of Phantasia. This game, published by Namco, is a precursor to tri-Ace's own Star Ocean games in several ways; i.e. an action battle system where the player controls one character and AI controls others in the party and special battle skills that the player can assign to different buttons. Besides the Star Ocean series, they also released Valkyrie Profile in 1999. Their most recent release, Resonance of Fate, was taken to SEGA for publishing.

tri-Ace games have sold over 3.8 million copies worldwide as of September 2005.[1] The company's sound programmer Hiroya Hatsushiba formed tri-Crescendo in 1999 which has since developed several games independently of tri-Ace.
