Just a note:
But this game introduced Lizard race that has no resemblance to a human female.
The visual appearance of female Lizards still consists of elements that can be decoded as 'female', so a 'human female' is still visually present here and will be actualized in some way (in most cases not in a firm sexual way I suppose).
The observation of 'male' players playing 'female' lizards shows quite well, as others pointed out, that the explanation of men just being visually appealed by female sex in video games always falls short for a great group of 'male' players.
