To get the above swag spread, you'd have to be madly in love with Persona 3. I am, but I don't know that I'd spend the money to get all of the above pictured stuff.
Someone in Japan bought six copies of this PSP RPG to get the bonus goods. There's shirts, calendars, posters, cards and more. There's even an Aigis pillow so that you may play out a perverted version of the Pinocchio story. Buying six copies of a game to get the freebies is excessive, but I understand. It would be better if you could buy the goods separately.
Atlus USA does a pretty good job of packing in the freebies. I wonder if they could fit all of these things in one deluxe box. At least pack in Aigis.
