QUOTE said:Thanks for your interest in Play For Japan, a video game industry-led effort to provide relief for victims of the recent earthquake and tsunami in Japan. The goal of Play For Japan is to encourage journalists, developers, and publishers to list unique and exciting items on eBay — with 100 percent of the proceeds being donated to charities that support Japan’s recovery. We then promote those auctions, so gamers can bid on the items.

Basically developers, publishers, and journalists are selling unique, (mostly autographed) items in order to raise money to support Japan from their recent disaster.
