No way in hell would you see 60-80% male voters pick female MC for an adult game where the MC is the protagonist trying to score sex with girls. Sure 90% of all female characters in most mmo games are actually male but come on..
You can't seriosly be saying that men want to be the girl trying to score a blowjob on other men.. unless you swing that way. But thats a diffrent topic.
First of all to Yggalf, you call bullshit and I'm gonna try to find the surveys, I remember that one of the ones that people participated the most was made on the ulfm forum and it was a clear majority for the female MC.
Back to John, your argument is very flawed. Are you saying that every single person that plays a hentai game with a female MC swing that way?, wow then Japan is fucked up.
First of all there are many things that female MC have in japanese hentai games that can't be had in male MC, one of those that is quite liked is cloth destruction, would you prefer a naked male or female?.
People don't use a female MC to identify with the MC but it's very different, most of the games in which you are a male MC in japan you are just a shadow, that's because those are made so that the audience can feel like they are the MC, however in the case of the female she is fully drawn and the focus is on the many situations and corrupted acts that the player can make her do during the game.
The majority of hentai games made in Japan are with a female MC, another big point that people like is the costumes, having the female MC be clothed on many different costumes that may be more or less corrupted and with quite a bit of exposure.
On the western side of hentai the creators at least are a bit more balanced (from what I have seen), I would say that it is a bit inclined towards female MC overall but it isn't a big difference, however most of the creators here don't follow the same practises as in Japan related to many female specific mechanics like some that I have said.
