I ask this question as yesterday I attended a panel for software and other media companies that was intended to show how the commissioning of games that feature the content of other media can make money. Attending the Panel was Dr. Jo Twist CEO of The Association for UK Interactive Entertainment, who at one point suggested that if Fifty Shades of Grey, could sell as well as it has then a good sex game should be able to do the same. She then cried out "Where's my Sex Game!"
If this is opinion of a women in a position such as hers I wonder how the software makers, the publishers and other industry members feel about the lack of a good sex game?
