Steam dropped a surprise announcement today when Final Fantasy X and X-2 were added to its games section. Square Enix will be releasing both Final Fantasy X and Final Fantasy X-2 to Steam on May 12. These Steam ports are the HD remasters that were made for PlayStation 3 and PlayStation Vita back in 2013, which were later re-released for PlayStation 4 exactly a year ago. These HD remasters include updated HD models, a remastered soundtrack and the content from the International versions of the PS2 games.
The specs and features can be found on the app page.
