A friend of mine told me about this game a while ago called Kagematsu, which in the rules requires cross play. I think here is the latest website I found for Kagematsu, but on this wordpress blog are rules from 2007, before the game became published.
This game reminded me of the cross-play post I made earlier this week. In the rules, there is one lone warrior wandering through the village that is played by a woman. The rest of the characters, regardless of gender, play women who try to get the warrior to defend the village. The question is why would the creator have the woman play the lone, wandering warrior?
I have a theory. This game is very dependent on a romance story line, and seeing if that story line succeeds or fails. Women are generally perceived to be more inclined to romantic notions. Just think at who the entire romance novel market is geared to, and which gender is expected to like random flowers, chocolates and other similar affections. Maybe this creator thought it would be easier to get to the love story element of the game if the person being desired really understood what makes a man desirable.
As I said, this is only theory. I would love to see what you readers think.
