Gamertell has posted a preview of Atlus' and Spike's PSP game, Kenka Bancho: Badass Rumble.
From the preview:
"...I recommend spending your first runthrough exploring and gathering intel. Beat up everyone you can. Explore Kyouto. Collect phone numbers. Try to avoid cops. Collect itineraries. Buy up souvenirs and outfits. Dress Takashi up as Banana Man before he heads out on the streets. Then, use your second playthrough to attempt becoming the ultimate bancho. There are also multiple girls the main character can end up with and a journal full of events to collect and complete."
