I don't usually post links to surveys and the like, but Aksys has an interesting study posted right now, and it's about female-gamer-oriented games like Hakuouki, Heart no Kuni no Alice and Hiiro no Kakera. Even if you have no idea what the hell series those are, if you'd like to see more otome games (i.e. any) hit the US market, let Aksys know. It's a very quick survey which seems to assume some familiarity with the original games themselves, making me doubtful they'll get much of a response, but it's worth a shot.
