Oh, absolutely play it. The biggest draw (to me anyway) of this game is the slow corruption and how you actually have to actually work to keep Karryn pure (but at the same time, you aren't punished if you wanna get raunchy as soon as possible).
Corruption/combat-H is my favorite genre combo -by far-, and way too many corruption games have a protagonist where you have to either go out of your way to start the corruption, or make wildly uncharacteristic decisions to do so ("gee, I bet absolutely nothing bad will happen to me if I wander down this dark alley with those three fine upstanding citizens waiting in the shadows") or they become omega sluts the first time someone accidentally lightly brushes against them.
Karryn's has the best tone and pacing of the corruption genre I've seen, and if anyone knows of a game that does it better or even half as good, point me to it (someone mentioned
