I don't really know much about the cuckolding themes as I'm generally not a fan of the genre. For example the direction of Liesel's story took me by surprise, as I never experienced the dev's other games.
I'm more of a moral degradation fan myself. I prefer heroines with strong principles that slowly eroded away, preferably through elements outside the player's control.
For this game in particular, most exhillarating aspect was being at risk of losing the investment in a character, either through the in-battle pins, or really tight inn management (which sadly seems to be trivialized if you have female mercenary + female story companion as they can tank all the dick)
