Peach Club Sekai Isshuu Quiz Hen
Publisher: Momonoki House
A game where you visit various locations around the world and meet stereotypical girls of those countries or areas. You then face them in a game show-like quiz contest, and they strip naked if you manage to get three questions correct in a row (wrong answers make you lose points). A decently-sized question bank is in this game, but the girls sometimes get answers wrong.
