Holy Invasion of Privay, Badman!? Don't worry if you did, because it appears NIS America is readying a spectacular bonus for the upcoming sequel. According to an Amazon.com listing, the "complete original game [is] included for free." Yep, it's two games for the price of one, and who doesn't like a promo like that?
It's unclear if this bonus will apply only to the UMD version of the game, or if the PSN version will also benefit. Considering how often PSP Go owners have been screwed, we wouldn't be surprised if the digital release arrived late with no discount and no prequel bonus.
