These various aspects have been positively received by critics over the series' lifetime, contributing to its overall worldwide success.
Final Fantasy began with the development of the titular first game in the series: developed at Square, later dubbed Square Enix after its 2003 merger with Enix.Final Fantasy was created as creator Hironobu Sakaguchi's last ditch attempt at success within the video game market: Sakaguchi had long wished to create a role-playing title, but the company had denied him the opportunity until then. The first Final Fantasy was released in 1987, and was a commercial and critical success that fueled the development of further titles. The series garnered international popularity with the release of Final Fantasy VII (1997) for the PlayStation, which became the highest-selling Final Fantasy title to date.Final Fantasy has become one of Square Enix's major gaming franchises; as of 2016, the series has sold 110 million copies worldwide across 48 video game releases.
