Oshiete! Popotan

Popotan is a Japanese adult visual novel developed by Petit Ferret with character designs by Akio Watanabe under the alias Poyoyon Rock. It was originally released as a PC game for CD-ROM on December 13, 2002 and subsequently re-released on DVD-ROM and for the PlayStation 2 with certain scenes removed.

Gameplay in Popotan follows a semi-predetermined plot; major events remain the same, but personal storylines can diverge from the player's choices. The game focuses on protagonist Chris, a drifter who meets three girls and their maid in a mansion near the ruins of Tokyo in the distant future. Popotan is a visual novel in which players spend most of their time in reading dynamic text, representing either dialogue between the various characters or the inner thoughts of the protagonist. After progressing through text, players either come to a "decision point" where they must choose from multiple options, or the text will end and the player must move to a new location, or, in the DVD-ROM and PS2 versions, use a shortcut option to continue to the next event.
