So, I literally never hear anyone talk about the FF games before 5 so I didn't include them...I can't imagine they were even capable of having good music anyway? I also only included numbered entries to make things much less complicated.
My favorite FF game with consistently amazing music is probably FFX. Despite that game's flaws and how dated parts of it are, I still find it incredibly charming to this day and a huge factor contributing to that is the incredible music. I mean how do you not get emotional listening to some of these tracks?
