ZeZipster what on Earth are you talking about? Square are not idiots, they didn't design the game specifically to make money from barely clothed females. It's simple logic:

Sex has sold for a long time, Square have never relied on it in FFs before, do you really think they would start using the ONLY FF that is specifically aimed at people who are already fans of the series?
Even if Square were that stupid why would they expect people to buy games based on that? If you want bare ladies there are far cheaper and more realistic ways to do it. It takes a lot of money to make a video game, I think they'd have thought it through.
As for Yuna changing, well as far as plot goes it would be completely ridiculous if she'd stayed the same after losing her love, her faith, been thrown into a huge position of power, went undercover, lost her main form of attack, had everything she'd been brought up to believe in taken away from her.....

I agree with Psychotic almost entirely, though I think Black Mages should be allowed to dress how they like. Simply because, why shouldn't they?

My only problem with FFX so far is that they picked two of the worst characters in FFX to keep and dumped all the good ones, including the only decent female.
That and that many FFs deserve sequels far more than FFX.
