"What Characters from PS 3 are worth keeping and why, how would you change them or replace them?"
Every character is worth keeping... Because they're the original cast, and core of Phantasy Star III rather they sucked or not...
Changing? Heeeere we go...
Rhys: He needs personality... We know nothing of him except he is aggressive and ready to start a war at the drop of a hat. I would make Rhys a cocky/arrogant fighter who fears nothing. That's how he struck me by his instant attempt to start a war with Maia's kid-napping.
Mieu: She should have more lines and a huge knowledge of Orakian history... Also her creator should be mentioned as well as her purpose... The Japanese version said she was only 560 years old, leaving her origin a complete mystery.
Wren: He should be more like Wren from PSIV... He should also have knowledge of EVERYTHING in Alisa III, why he didn't is beyond me... And why you had to learn of his transformations from townsfolk and not Wren himself is beyond me as well.
Lyle: Lyle was cool! I'd keep him much the same, but maybe have him explain more behind his motives... He should also be able to transform into a dragon, seeing as... You know, he can transform into a dragon!
Lena: Lena and Rhys should have a history together, and she should be of a noble Landen decent. Perhaps the castle that later becomes ruins next to Landen.
------------------
Ayn: Ayn should be a famous man... He is the first Orakian/Layan fusion, and he should have close relations to both Landen and Aquatica. He should be a gentleman. A real prince.
Thea: Thea should be more of a wizard-type mage using Slashers... She is pure Layan and daughter of Lyle afterall... Thea should also have a weaker dragon transformation ability.
Sari: Sari is the heir to the Landen thrown, she should be made a pure warrior, and she looks like an Amazon... Maybe make her like Xena warrior princess! Dunno...
Nial: Nial is pure Orakian, he should be much like Rhys, or maybe even much like Sari but a male... I always found the two of them very similar... Maybe cause Lena is the mother?
Ryan: Ryan should be one of those "I'm glad he's on my side!" kind of people... He's a rebel, so keep that in mind when making his character.
---------------------------
Adan & Gwen: They should be shocked by the worlds... They grew up on a colorless moon, they should be kind of like Rika. They should also be very educated! They should also have some extreme telepathic connection with Laya being their mother, and them being twins.
Aron & Princess Kara: Similar to Adan and Gwen, they should be raised borderline war monger like warriors. Just figure, Nial is the dad, Alair is the mom, and Lune is there as well. These people would be super warrior mentality.
Sean: He should be gloomy and hateful for obvious reasons.
Crys: He should be the ultimate warrior type, growing up in his era in Landen would form a true warrior. He should be kind of a prick with a smart mouth as well.
Warrior Kara: She should show loyalty to Laya, and be much like Lune. She is a warrior Kara after all.
Laya: The result of a magician who spent her life in a endless and hopeless war where the end result was her sister and worst enemy gave their lives to save their ship.
Which Generation needs the most redesign, what would you do?
All 4 third generations need heavily changed, and the 2nd half of Nials should be changed as well. Those parts are ALL the same thing.
I've traveled back in time... 300 years... Just to call you a "Cracker"!
