Bish?jo game, you ask? It is a "Japanese video game centered around interactions with attractive anime girls." In the latest issue of Dengeki Daioh magazine, it was announced an anime adaptation of the 1998 erotic dating-sim White Album will be released along with a PS3 game based on this version. The original game was unusual for a dating-sim because the main character already has a girlfriend. A scan of the magazine can be found here.
Considering the abundance of such games in the PS2 era, we are not surprised this genre is starting to take off on the PS3. In a way, it shows that the PS3 has reached a wider audience and is becoming more mainstream in Japan.
