I guess they did, they certainly had the most memorable, though it's not as technical as some stuff I've heard. Nobuo Uematsu's style isn't overly complicated, he keeps it simple and memorable. That's his appeal ^^
Here's my best list (I'm hoping to incorporate some of this stuff into my own study

)-
To Zanarkand (FFX)
One Winged Angel (Comp FFVII, AC version is best)
Liberati Fatali (FFVIII)
Aerith's Theme (FFVII)
Cloud's Theme (aka FFVII Main Theme)
The one mentioned which was a piano version of Those Who Fight Further, the battle theme from FFVII
Suketi Da Ne orchestral version (FFX)
Most of the stuff Uematsu writes is heavily thematic, he tends not to try and pad it out with trills and such very often. Yet it still sounds epic. My advice is to check out the Tour Du Japon stuff on YouTube to really get into the orchestration of the music, makes analysing it much easier.
Hope this helps ^^
