I completely agree with that.
Allowing the companions to have their own agency and fun beyond the main character opens up the chance for a lot of creative writing. There are a few scenes currently like that in the game, but most of it is still experimental as we get a grasp of a creative process that works for us. Morrigan, for example, has a few options currently in the game where you can encourage her to have fun with others. At the same time, someone like Tera is a bit more hesitant about the idea, and then there is Celine, who is much more of a traditional romantic.
Sex positivity is a big goal for us, which means exploring many facets and preferences for the player and the characters alike in the game.
We do plan on adding more options like that in the future, and most of this content will be available in the base game.
The Nymphomania mode, as the name implies, merely dials some of the lewd options into overdrive and leaves plot and characterization behind for the sake of some good old-fashioned smut. (and play testing in this early stage of development)
Ultimately, it is impossible to please everyone, so our focus is simply to create scenes and characters that we feel would make for an exciting and compelling addition to the game.
