Boys' Love (BL) games usually refers to otome games or H games oriented around male homosexual couples for the female market. The defining factor is that both the playable character(s) and possible objects of affection are male (BL stands for Boys' Love). As with yaoi manga, the major market is assumed to be female; in addition to BL games proper, many otome games have incidental homoerotic content. Games aimed at a homosexual male audience may be referred to as bara. A 2006 breakdown of the Japanese commercial BL market estimated it grosses approximately 12 billion yen annually, with video games generating 160 million yen per month.
