Yesterday I started a topic on the forums for the game company xseed in hopes of convincing their company to localize
"Gakuen Hetalia" for the psp. I believe that if enough people ask for it then they will localize the game. If you
would like to see "Gakuen Hetalia" localized then join the xseed forums and show your support by posting on this
topic.
