Chrono Trigger (??????? ,Kurono Toriga?) is a console role-playing game developed and published by Square (now Square Enix) for the Super Nintendo Entertainment System in 1995. The game's story follows a group of adventurers who travel through time to prevent a global catastrophe. Square re-released a ported version by TOSE in Japan for Sony's PlayStation in 1999, later repackaged with a Final Fantasy IV port as Final Fantasy Chronicles in 2001. A slightly enhanced Chrono Trigger was released for the Nintendo DS on November 25, 2008 in North America and Japan, and went on sale in Europe on 6 February 2009. It has never been released in PAL territories on the SNES or the PlayStation.
Chrono Trigger's development team included three designers that Square dubbed the "Dream Team", consisting of Hironobu Sakaguchi, creator of the Final Fantasy series, and Yuuji Horii and Akira Toriyamatwo freelance designers known for their work on Enix's Dragon Quest series. Kazuhiko Aoki produced the game. Masato Kato wrote most of the plot, while composer Yasunori Mitsuda scored most of the game before falling ill and deferring remaining tracks to Final Fantasy composer Nobuo Uematsu.
Chrono Trigger was well-received by reviewers and commercially successful. Nintendo Power magazine described certain aspects of Chrono Trigger as revolutionary, including its multiple endings, plot-related sidequests focusing on character development, unique battle system, and detailed graphics. The game's SNES and PSX iterations have shipped more than 2.36 million copies in Japan and 290,000 overseas as of March 31, 2003. Chrono Trigger DS has shipped 490,000 copies in Japan and 220,000 in North America as of December 2008.
