Love this game.

I'm on the third disc, right after (SPOILER)you go to Lindblum castle and Cid gets turned back into a human and it's been a great ride so far. My favorite moment up to this point was when (SPOILER)you find Eiko in Mt. Gulug and Zorn/Thorn try to summon an Eidolon from her, then Mog comes to the rescue, turns into an eidolon herself, and uses an attack called Terra Homing on them. That was possibly my favorite part of the story so far.
