Everyone always lists 7 as their favourite or the best one of all time, but in all honesty ffix is the magnum opus of the series. The setting, the characters, the music, the story and everything else are all top quality.

It originally released towards the end of the ps1's life as champion of consoles since the ps2 was around the corner (outside of japan) and a lot of people missed it, which is fair enough. But if you're a fan of final fantasy and jrpgs this is a must play.
