I just like games based upon their battle systems. And FF7-9 all had basically the same battle layout (at least in FF9 you got to have a whopping FOUR characters battle), and that layout was way to bland. "Attack" -> "Monster". Sure, that's what FF3 did too, but I liked the side-view of the battle and how the battle just didnt come to a complete stop when someone cast a spell or something like all the flashy effects in FF7+. Basically I just liked how the characters in FF3 jumped out with whatever weapon they had and attacked, especally swords like scimitar, which looked really weird.
After playing games with great battle systems (Grandia 2, FFT, ToD2, and other PC rpgs) it's sickening to go back to the lame battle system that plagues FF7+ and games like Wild Arms 2 (that game took the battle system to an all-time low). It doesn't look like Square will ever get rid of this kind of battles though, so it looks like I need to find an Enix hat and put it on.
