Ever been asked a question regarding biographical information about a Sanrio character, but you can't answer because you're too far away from your extensive Hello Kitty database? You're in luck, if you get into that very unlikely situation in the future, and you can read Japanese!
Hello Kitty's Fashonable Party contains biographies of 300 Sanrio characters, with info about their birthdays, favorite food, and ... probably other stuff too. The game will quiz you about this stuff, presumably so you can memorize it. Fashionable Party also contains a dress-up mode and, predictably, a spate of minigames as well. In this case, though, the minigames are probably welcome since they bring the only actual gaming to the Party.
