Nor do I.
Hmm... retopicing mute heroes, I've noticed a thing while playing Golden Sun 1 & 2 (not as good as FFV but is possible to play on the bus), in game 1, the main character is Isaac, who is silent all the time (except when saying "yes" or "no" to stuff, which ONLY affects the next line of dialogue...), and Felix has a few lines. In GS2, you play as Felix, who is (except when saying "yes" or "no" to stuff, which ONLY affects the next line of dialogue...), and when you meet Isaac, he has lines.
Why can't the main character speak? Hey, I don't have trouble identifying myself with talking heroes (unless they're way to odd, e.g. loves to kill hamsters with miniguns or sumzin' worse...).
