Questions about questions - I wonder I could answer all, but I´ll try and start:
1) Nope! I don´t think that these basic game mechanics will ever changed by Illusion. And the BetterRepack is only a modding platform and doesn´t affect the game itself. Maybe someday good Modders do the work adding new animations and story adds.
But you can try a look on the newest game Room Girl
https://f95zone.to/threads/illusion-room-girl-character-sharing.132181/ and also yet on BetterRepack
You must be registered to see the links
2) No clue what you mean, but an Autoplay mod I didn´t see so far
3) Don´t know - never used Cheats. But there is a chaeting mod, but no clue what it´s doing
4) no new Hanmen beyond that
https://f95zone.to/threads/next-gen-skin-textures-v1-01-hanmen.91701/, but this isn´t forced the top, others prefer the skins of K1T0-K1TN or Nyaacho, all part of BetterRepack.
5.1) I know, you´re looking after something as "Batch Build" in Skyrims BodySlide.
Nothing heard about and I´think impossible. Cuz the skin is saved on the card you ever have to overwrite it with a new save.
5.2) Well, HS2 IS NOT Skyrim! Otherwise see Item 1) "Room Girl".
6) I have a mod (Plugin) called "CumOn" that can control male cumming, but unfortunately didn´t store the link
Nevermind -
it´s a helping thread
