As someone who doesn't like pointless pervy nonsense in my media... I still think it's wrong to prevent a game like this from releasing in the West and/or censorship. If I don't like it, simple, I just don't have to buy it. But other folks do like it and would want it. Just because I don't like something doesn't mean other folks shouldn't be able to have it. I'm not interested in MOBAs or RTS, but that doesn't mean those games should be gotten rid of just because some folks don't like it. As with most things in life, there'll always be different opinions. The biggest concern here is, is this hurting anyone? Unlike things like micro-transaction and over-priced DLC which affects enjoyment of a game, I don't think anyone is exactly losing sleep or in pain over the existence of this game.
I know it's annoying, but sex (or rather the lack thereof) sells. People didn't complain about games like the Witcher and Bioware games that much, why are they putting on a double standard for this? I guess one could argue that those games had the context of actual sex (that actually happens) to justify such inclusions and that the pervyness in these DOA games don't have much of a purpose besides 'look boobies!' Heck, it's one of the reasons why I don't particularly like these games. But is it really hurting anyone? I don't think chicks have to worry about their boyfriends being more interesting in DOA chicks than them, it's just images on a screen. If if that is an issue, just dump the guy and get a better boyfriend who has a grip on reality. It's not like there hasn't been games where men have been similarly sexualised, I'm thinking of that Iron Bull character from Dragon Age right now. So what he shouldn't be in too?
Imagine a world without porn... sure it might be nice in some ways, but in other ways there'd be a lot of trouble brewing. Stuff like this keeps young folk entertained and out of trouble. Better for hormonal adolescents to gawk at pixels on a screen than to leer at actual real people and make them feel uncomfortable. A necessary evil? Perhaps. Though evil is too strong a word IMO.
