The Yakyuken Special is a cult classic "adult" FMV (Full Motion Video) game released in Japan in 1995. While often associated with the PlayStation 1 in retro gaming circles, it was primarily released on the Sega Saturn, 3DO, and Sega 32X. It is best known for its "bizarre" presentation and its notoriously difficult AI. Game Overview and "Story"
The game is based on Yakyūken (Baseball Fist), a traditional Japanese drinking game centered on rock-paper-scissors accompanied by music and dancing.
The Goal: You play rounds of rock-paper-scissors against various women. Each time the player wins a set, the opponent removes a piece of clothing.
The Catch: Unlike standard rock-paper-scissors, the game is famously unbalanced. Some players have reported winning as infrequently as once in every 50 games.
Narrative: There is no traditional "complete story" or plot. Instead, the game is structured as a series of matches. Success leads to rewarding dance sequences and FMV clips of the models. Files for CHD-PSX-JAP - Internet Archive
