Do you prefer the rich/famous Princess/Knight getting turned into a sex crazed slut, or are you more a fan of the niave new kid in town who is slowly degraded?
I like the slow-burn stuff like GGGB and AWAM. Especially when you get options and it's not just a linear series of scenes. And honestly, by the time it gets to the slut mode, it has long passed its peak of interest for me. It's all about the gradual transition.
I like them being corruption, not brainwashing. They should free the girl's mind, slowly releasing the desires hidden deep inside her, and not turn her into a brainless whore.
neither. a strict mature soccer mom getting slowly pushed over the lines of decency she's spent all her life guarding. and slut level should never be reached, she should always stay a little guarded and reluctant to comply. if there's no resistance there's nothing to corrupt.
I think both concepts work just fine for me. What's probably more important is the journey. I prefer a gradual descent but with a few spikes (dips?) thrown in to keep things interesting.
