Just a short while ago, we received an email from MangaGamer, a distributor of English-translated Japanese adventure games. It contained a press release for an adult turn-based card battler entitled Boob Wars: Big Breasts vs Flat Chests. The following is the game's story synopsis:

At the beginning of the 22nd Century, an anomaly began occurring in the bodies of women...

All the women of the world became either E Cups and up or A cups and under. "Big Breasts" and "Flat Chests"...

By their division into these two groups, the debate over which was superior began. After the first incident of armed conflict, known as the "Nyuuhen Tragedy," the entire world was split between the Big Breasts Tribe and the Flat Chests Tribe and an intense conflict ensued.

87 years later...

The secret organization of Erorists, "Eagle," has ordered our protagonist Takamura Manabu to pursue the mission of his career: "Seduce Queen Milk Elioto of the Big Breasts Tribe and Queen Teresa Premadasa of the Flat Chests Tribe and bring this war to a close."

"Eagle" immediately sent the Erorist, Takamura Manabu, to the two queens!!

Game of the Forever.
