I don't play "good guys" because I don't find stories about good vs. evil very interesting. I'm in the camp that doesn't find such characters realistic as conflicts rarely work out so neatly in history, in my opinion. I think the biggest reason I like the Game of Thrones books/show is because the traditional hero and his hero's quest don't really work in that world. (Unless you're Brienne, but her story interests me because she is the most chivalrous and honorable character, but nobody takes her seriously 'cause she is a she, but that is off topic.)
But Final Fantasy is your fantasy, so put together a group of heroes if that is the type of storyline you like! I'd just encourage you to have a reasonable backstory for why your character has such a moral compass. I find it unrealistic when fantasy characters have values very common in the 21st century in a world where those values are not the norm. (There is an article about modern values in fantasy settings on this fantasy-writing Live Journal, but I forget which article it is.)
