(SPOILERS!! Don't read until you have completed the game)
Ok I personally thought he wasn't the main character. i thought that Ashe was more the main character and Penelo and Vaan didn't get enough coverage and just appeared to be tag-along's. There wasn't anytime where Vaan did something really heroic, (Like save Penelo or Ashe or something) he just seemed to be one of those hero's who just didn't get the chance to show his heroism (I think there should have at least been a bit where Vaan fights Vayne alone but meh) The only thing i thought showed him as the main character was that he is the character you have to control in towns.
Anyway topic;
Do you think Vaan was the "main" character? (Yes i know he was but do you think he was treated like a main character?)
