Slashing the characters feminises the characters, not the genre, in my experience. The inherent masculinity might be reinforced but it is also altered. And it's sex, not action-adventure, that becomes a boys-only
game,
and one with precious little action-adventure in it.
AVON: Time and again I've longed for adventure, Something to make my heart beat the faster. What did I long for? I never really knew. Gazing at you, I've found my adventure. Touching your hand, my heart beats the faster. All that I want, in all this world is...you.
