It's just great when that last one gets to its most triumphant part just as we're shown the four heroes, one after another, fighting an enemy and going into a close-up and freezing while a list of their level and the abilities they've learned scrolls by.

The ending can't be altered that much, really. One difference is that there are different abilities listed on the final ability list every time you play and beat the game (depending on what you've learned), and another difference is how wounded/petrified/zombied characters stay behind in the Void when the others escape. This changes the memory scenes in "A letter to Cid" scene a bit, but it doesn't change the storyline since the characters who were left behind will return anyway when you visit the big tree. Oh well, FFV's ending is still a very good one. There isn't many bad endings in the series, IMHO.
