This game has a good story, great combat, and an interesting world. The ONLY reason you think it's for wanking is because the women characters in the game are all dressed in fetish gear and lingerie despite there being no mention of sex or sexuality anywhere in the game. It's pure fetishization and it's especially creepy on the two different characters who look underage.
Point being it's a pretty good game with overt and put of place fetishization of specifically women characters and that's why some people have an issue with the sexualisation. Every male character is covered head to toe, most of them even have full head mask/helmets. The game isn't sexy at all - a side character mentions love and Eve literally doesn't know what it is - other than the outfits.
