I don't like Akihiko's english voice in P4A. It's not the same as P3P. That alone was enough to make me not main him even though he was my favourite in p3p.
You're obviously just distracted by Aki's bare chest. It's the same guy.
I'm convinced after P4A that P5 will have an action/tales like battle system.
I'm not sure how I feel about that but could be great with the series enemy designs. Crazy?
Not necessarily. I could envision an action/RPG persona. I don't think they're going to do that anytime soon though if SMTIV is any indication.
