A "sexual object" that is as empowered as her male counterpart and that's before remembering that her outrageous proportions only exist in the realm of fantasy, something that most "gamers" can tell apart from reality.
And this culture you speak of is affected far less, if at all, by a fantastical self empowered unrealistically proportioned sorceress than real world issues such as birth control, reproductive rights etc.
The game is Japanese and once again, their daily cultural pertaining to gender notwithstanding, their adult animes (such as witchblade, sekirei etc) portray generously well endowed women being capable of biting back just as hard if not harder than men.
I have already mentioned this before, but I think it's worth repeating that you got yourself in a bit of cultural divide. For example, afaik, games developed in JP feature far more self empowered female characters than in the west. In recent times ME, TR, The witcher 2, DA franchise and ME come to mind in the west and as for east, we've got Bayonetta, FF13, LO, Persona, Disgaea, RE, NG, Star Ocean, VC, Ni no kuni, Tales games, Star ocean etc.
Plus, I wonder how many game concepts are threatened to oblivion because they feature
female protagonist?
