Ashe is really the main character
I’m not sure I agree here. True, the story revolves around her decisions; but almost always, someone or something else gets her to change her mind; and surprisingly easily too. Heck, at this point in the game I’m STILL not sure why she’s seeing her late husband’s ghost, or why Vaan can see it too (?) As you pointed out, just being the focus of the story doesn’t make a character the ‘main’ one.
I’ll give FF12 this: it’s a more realistic take on this kind of situation (e.g. “should a conquered Nation fight for its freedom, or seek to coexist with its new rulers?”) than most games would aim for. Though the sudden turnabouts in the story’s direction (“We must fight the Empire! No wait, too many lives will be lost! No wait, we DO have to fight it after all!” etc.) are too annoying for my taste. Good plot, poor execution.
As for Fran, she’s TOO much of a mystery. They can retain her mystique without teasing us about facts that never get revealed. I found the whole bit in Eruyt village, between her and her sisters, very infuriating, in that they kept talking about how great being in rapport with The Wood is, yet also many Vieras feel they “have to leave” but later regret it yet know they can “never return.”
As for Fran and Balthier being lovers, that’s the basic assumption, but I have yet to see them exchange anything resembling a loving remark, not counting sarcastic comments. That’s unusual even by the culturally-shy standards of the Japanese. It’s OK to me if they are just partners who just happen to be of opposite genders, with no love or sex going on, but I wish they’d just state it clearly.
Btw, sorry if I sound too critical, folks, but keep in mind, I’m a writer by nature; I don’t always see stories (even in-game ones) quite the same way that most people do; I tend to notice plotholes and character flaws right away.
sorry if i’ve spoiled anything in my previous posts, it’s easy to get careless when you’re trying to make a point sometimes.
He don’ know me too well, do he? Oh well, he’s new around here. 
Flint, as most folks are tired of hearing me say by now, I’m immune to spoilers! So much so I often check out the ending of a story FIRST just to make sure I’ll like it; it’s not so much that I don’t like surprises, as that I HATE the bad ones. Thanks for caring, anyway. Do tag any real spoilers for other people’s sake, though.
