I agree. While Final Fantasy is not nearly as bad as other JRPG franchises, I think some more mature themes and less archetypical plots and characters would do the franchise a service, especially as it appears to be getting stale with my many increasingly older gamers. Keep in mind, the "Golden Age" of Final Fantasy is now older than a rather large demographic of video game players themselves and those who appreciated the games IV-X are now in their 20's or even 30's.

To be honest, I would like to retire the teenaged protagonists and world-saving plots a bit for something a little less wholesome. I'm not saying we go all M-rated and make a Gears of War RPG (I'd argue that would be going backwards), but some moral ambiguity and more nuanced handling of violence, sex, ethics, and the like could do the franchise good.
