I saw this in artificial girl 3 from illusion. an external program that is compatible with the base game. U thought something like this for xstoryplayer could work well. especially for those of us who know next to nothing about scripting. The core idea is, make a noddle in the character maker, then import him/her ubi xstoryplayer. created characters could be accessed through fastsex mode. Moddec clothing and other things could also be handled through a system such as this.

From following this forum i can tell you that's already an integrated feature.
Unlike ag3 or any illusion game, this game will support modding. The reason those games need a separate character creator is because the base game doesn't support modding. So you have to mod the gamefiles with a separate program.

As of now its still unclear how much the clothing and models in the game can be edited, I'd assume the physx aspects really limit the possibilities of changing the character too much, I'd also assume things like clothes, hair, heads, skin colors and bodytypes will be possible to interchange in a selection screen but changing the shape of those character models will be much more complex. so i don't expect any sort of slider system. I'd assume and hope there is a way to make your own character models and import them as mods. I know objects will be importable but i haven't heard much from the devs about actual in game character models being replaceable.

A wiki will be created with tutorials on how to edit/create characters.

We will try to make it as easy as possible, but it will require some modeling/3d skills.

3d modeling skills i have =) so I'm very happy to hear that.
