I think part of the reason that there is so much sexual/gender ambiguity in games recently is that game designers have cottoned on to the fact that girls like video games too, and not just in a 'Barbie pony palace' capacity. Well done, I'll give them a badge since they don't have a chest to pin it on. However, said designers seem to believe that girls would like games 'just like for the boys only with pretty men in too' and while this isn't completely wrong, it's wrong in several significant ways and so I find it insulting.
And why has Japan been so big on the gender bender/sexuality??? deal for so long? I think it's because they're more aware of the fact that it's all FANTASY and can put in what they like to spice up the setting with 'what ifs' and 'maybe it's this' and don't nail down genders and sexualities because it'd get in the way of imagination. Imagination, it's like making stuff up in your head for enjoyment or creating things and has no need to be tied to current reality nor anyone else imaginings.
PS: Yes there is such a word as infanticide. Selective female infanticide is a currently practiced in several major countries and has a long history showing that the practice usually results in/is caused by epic societal dysfunction. If people world-wide stopped being awful to women the world would be a lot different and I dare say better.
