I won't deny the truth in the article, but the girls I play in games have no big breasts (Personal preference.
) and are decently armoured. Not that I eshew scant clothing, but I try to get what the character in question would wear. I don't mind naked legs, since I can imagine it would be due to mobility issues. (Compare to Roman Legionaires.) However, a cleavage a mile deep and exposed midrif is a bit too far, since it would also expose the heart, lungs and abdomen, for starters.
All in all, I don't mind the "scantly clad heroine", not at all, but I do mind it when it's the only option.
As for the help you get in MMOs if you play as a girl, that's true. I never abuse it, but I noticed I could have, if I wanted.
