Hmm, I think you're going to need more than 4-5 scenes per game

FFVII - Can't really think of one right now. Maybe later.

FFVIII - (I can't believe nobody has mentioned this before me!) (SPOILER)The fight between Galbadia garden and Balamb with the galbadian army, all the SeeDs fighting, basically everything. And the music was great!

FFIX - (SPOILER)When everyone is fighting to save Garnet in Alexandria and Beatrix joins your party. Alexander vs. Bahamut, also great. Oh! And when entering Memoria and the fight with all the Silver Dragons.

FFX - (SPOILER)When the party crashes the wedding, or right before you fight Yunalesca with Auron's line and all that.

You know, FF has too many good scenes in it for someone to just pick one that's best
