"At the beginning of the 22nd Century, an anomaly began occurring in the bodies of women," so goes the tale of Boob Wars. "All the women of the world became either E Cups and up or A cups and under. 'Big Breasts' and 'Flat Chests' ... Due to 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."

I have seen the conclusion of this story by playing Boob Wars: Big Breasts vs. Flat Chests. My reward? An overwhelming, intense feeling of self-loathing. I think I hate myself entirely, and I owe it all to the fine people at Manga Gamer.
