Actually all 3. Depends on the mood. If I just want to play the game, since it actually is one, I play on Prisoner Mode, Pure Build for the Challenge. If I just want to see the sexy stuff, Warden Mode Slut Build, since Prisoner Mode isn't a challenge with a Slut Build. And then sometimes I go with a inbetween, which is basically slow corruption in which MC tries to cling to remain a fighter, while getting more corrupted with time. That one is basically Prisoner Mode, but with some "rules" to make sure, that stuff happens to her, here and there.
