Female PC would mean adding male characters in game. It would mean complicated hoops to go through like Superman 64. Then there is a load of redesigning for poses, adding bulging... Adding plot that give you explanation as to why all these men (and women) are in your basement. Plus the need for actually adding hands for PC model... Design a head, to give head... It's a lot of work.
Maybe 4th version could support it...
Though I'm not against the addition of male NPCs, there's no strict need to add males if you're playing a female PC. Lesbians do exist. And I also fail to understand why you think there would be a bunch of complicated hoops. We can't even perform oral on the female toons yet, so I don't see any special reasons why xmoon would need
to add that either.
Also, why would be need any particular plot added? We have a futa. Nothing explained there. It's just a new feature to play around with, as this thread's suggestion would be.
All that aside;
And how (pardon my german) would they fuck?
Strap-ons. We have 'em in the game already. Hell, even the regular oral commands would work on it, if you wanted that.
Personally, I'm indifferent to having a female PC. I'd probably play with it if it were available, but it's not something that I would demand over more stories or the other improvements being worked on. Would be nice to get cowgirl added in the dungeon though (hint hint) :p
*edit, forgot something*
and main character have use of the real hands....
Take a look at the HTC Vive. Those controllers would be frigging bitchin' in this game. I've seen how well they work in a virtual space. Right now, I think the mouse serves its purpose well enough for what we have, but if xmoon added support for the Vive, I would be quite happy when I get it. Well, if I get it. VR seems to be the new big thing, so companies will certainly try adding gimmicks to their product to make it sell better. Though the vive has pretty much everything one would need in a VR setting.
