As one of the most-requested remakes of a Final Fantasy game, Final Fantasy 6 should follow the approach taken by the upcoming Dragon Quest 3 remake.
Aside from being the game that was largely responsible for popularizing JRPGs in the West, Final Fantasy 7 was many players' first game in the series and has long been the game that is most recognizable in the franchise. Given its place in the series' limelight, it makes perfect sense as to why Square Enix chose to remake FF7 for modern audiences with Final Fantasy 7 Remake and the upcoming Final Fantasy 7 Rebirth. Still, there is another (and perhaps greater) Final Fantasy title that has an oft-requested update: Final Fantasy 6, As the greatest Final Fantasy title from Square Enix's legendary SNES catalog, Final Fantasy 6 is more than deserving of its own remake.
Releasing on the SNES in 1994 as Final Fantasy 3, Final Fantasy 6 is widely regarded as not just one of the best Final Fantasy games but also one of the best RPGs ever made. Featuring a shocking mid-game plot twist and some series-best mechanics, Final Fantasy 6 is a fan favorite that seems to only get better with age, further evidenced by its popularity among the 6 titles on offer as part of the Final Fantasy Pixel Remasters. If and when Square Enix decides to remake Final Fantasy 6, it should implement the same template used for the upcoming Dragon Quest 3 remake instead of the full-3D re-imagining afforded to Final Fantasy 7.
