HIGHLIGHT TO READ AT YOUR OWN RISK!! (SPOILER)Actually, i think the Good Ending is better than the Perfect Ending, because in the Good Ending, we have the feeling Tidus is going to stay for GOOD! But in the Perfect Ending, we have the feeling that Tidus MAY vanish again. The Sad Ending is when Yuna learns that she has to live without Tidus, that Tidus would only be in her heart. The Bad Ending is...well...when you lost against Vegnagun.
