It won't. Unlike a certain Japanese company called Telenet - who once did the Valis series - they weren't in so big a financial trouble that they relinquished the rights to a company that specializes in hentai games.
In Koei-Tecmo's current state, that ain't gonna be an option anytime soon.
that's a strange constant fear to have, i assure you that ogling the DOA ladies in skimpy outfits while they write around on a bed will be the farthest team ninja will go, plus there is not as much money in porn as there is videogames, so financially it wouldn't make sense
They won't. Like it was already mentioned making DoA a legitimate porn game would make the series niche as fuck and would make them lose money. Not to mention half the appeal for their targeted fanbase is them blurring the lines of ecchi and hentai not crossing it.
Not even the most desperate niche game developers make full blown porn. Why?? Because a higher CERO rating than D, Z, makes the game sell less, and because straight up porn games can't be sold on normal popular game shops.
Also, I just checked and all the Z rated games are Western games. I guess it's mostly a rating for extreme violence.
Yeah it won't happen, DOA is a fighter and that'd split the base plus it'd be ridiculous. They use fanservice but aren't gonna suddenly do something rash like make Eliot fuck Kasumi.
I'm not a shipper, but Kasumi and Eliot don't even know each other for all i can remember. And Ayane and Eliot, i could see the writers going foward with it, but i think the DOA story is like a shounen where everyone stays single forever even having sexual preferences.
In Koei-Tecmo's current state, that ain't gonna be an option anytime soon.
