1 - The characters are created with the same software used by the developers of the two games in your signature, but proportioned to represent (to a certain extent) how 'real' women look. You could, if you take a moment, swap many of the faces between characters in this and your 'signature games', and most people wouldn't notice at first glance.
2 - Some people, including me, like to look at and fantasize about 'obtainable' women and not the Barbie dolls in many games.
3 - You are indirectly insulting everyone that does like these characters.
Serious question: could you not figure this out on your own, or did you just come here to crap on fans of the game?
