I'm not sure why he finds it so hard, I think it has aged really really well. It doesn't really have many or any clunky difficult mechanics. Gameplay is fast(for a turn based jrpg), simple, doesn't require long explanations or a guide book, and you don't have to grind like other jrpgs as long as you kill everything on your way to the next story point.
It still looks good and the music is good too. Unless you just don't like 2d sprites or turn based combat even if it's easy, I will wager you'd still enjoy it.
Interesting I don't think I've seen anyone call it the best before. I loved the shit out of ff7/9/10 and was so excited for 12 and it was one of the first big gaming letdowns I can remember. Ive still had the heart to pick it back up.
