Gotta say I love Larsa Solidor. It's nice having a protagonist who is both very intelligent and eloquent. While we all know Square loves their young heroes, picking Larsa takes it a bit further by being quite a bit younger than every other main character in the series. We cannot forget his deep connection the game's story and conflict what with being heir to the Evil Empire of the game as well as brother to the primary antagonist. While he was far from a wuss or coward he had some understandable trepidations about fighting his own brother but he manages to overcome them in teh game. Some wonderful character development there.
FFXII is an amazing game, made even moreso by Square's genisu choice of leads.
Now back to reality.
What the Hell, Square. You wanted a young, good-looking hero as the face of your game? Fine. YOU FRICKIN' HAVE ONE. He's awesome. He dual wields. He's better than almost every character we actually ended up being able to play.
Forget Vaan. Larsa fit all the petty requirements while also being a great character.
