Currently playing this game for the first time on my iPhone so I've skimmed over the responses to avoid any spoilers.

I've just gone through the class change which is definitely one of the biggest highlights so far. The sprites on this version have clearly been spruced up since the days of the NES but my characters now look awesome!

I have to agree as well that the airship rising out of the sand stood out for me. Though they must find sand absolutely everywhere! I bet that ruins their bacon sandwiches in the morning.

I was actually quite thrilled to meet the first incarnation of Bahamut having kicked some serious arse with him as a summon FFVII.
