Women. After all, most women I know of are serial killers or housewives that need to let their aggressions out from time to time (after all, beating your own kids is, sadly, a very serious offence, though those bastards would deserve a good beating every once in a while). Stories and character interaction? Women got enough of fairytales in their childhood. Romanticism and sensual content? Nah, most women who are into gaming watch porn as their husbands have become impotent. Most girls I've talked to find lesbian content particularly exciting, and it is a major factor in their purchasing decision...
Spoiler:OK, so actually I voted men.
