As of September 2021, the Final Fantasy X series had sold over 20.8 million units worldwide, and at the end of March 2022 had surpassed 21.1 million. The collection did receive criticism for a few minor upgrade faults and uneven quality between the two, while some of the collection's added content drew mixed opinions. Many critics praised the graphical upgrade and the chance to play through the games on the new platforms. The collection sold favorably, and received positive reviews. It was released for the PlayStation 3 and PlayStation Vita in Japan in December 2013 and worldwide in March 2014, for the PlayStation 4 in May 2015, for Windows in May 2016, and for the Nintendo Switch and Xbox One in April 2019. The Chinese studio Virtuos handled large parts of its development, while Square Enix assisted the process and published the collection. The collection saw graphical and musical revisions and is based on the international versions of both games, making certain content accessible to players outside of Japan for the first time. It also features story content previously only found in the International versions, and a new audio drama set a year after the events of X-2. Final Fantasy X/X-2 HD Remaster is a high-definition remaster of the role-playing video games Final Fantasy X and Final Fantasy X-2, originally developed by Square (now Square Enix) on the PlayStation 2 in the early 2000s.
