Attention my fellow escapists:
The "ass" line has been used over 8000 times in this thread alone. It's no longer witty. Not even when quoted ironically. Anyone else with nothing further to contribute can save themselves time and energy by simply typing the words "ass line." Since we've all memorized it, we'll know what you mean.
On topic, I occasionally play female characters simply because I like female warrior-types, provided they're done in a way that isn't terribly exploitative.* It's not even a sexual thing, I've just always enjoyed characters who combine class, elegance and grace with an ability to rip out your skull and beat you to death with it. I like my male characters to approach this from the opposite direction: in short, I like (and empathize with) characters who have a mixture of masculine and feminine traits,** and find it harder to get into the heads of characters at the extreme ends of that scale (be they super macho space marine types or girly girls).
*I personally use the Dante Rule to determine when fanservice has crossed the line. In short; is the female character under scrutiny more exploitative of women than Dante (he of Devil May Cry fame) is of men? If so, the character in question probably takes things too far.
**The proper term for this is androgyny, but on a video game forum, people associate that with JRPG characters, and that isn't what I mean. At all.
