Well I am not going to pretend to know how to write erotically, there is so much more than putting a dick into a hole. While corruption of champions II cater to a number of fetishes, it almost seems tame compared to TITS or even its predecessor. Ball sucking, food play, foot play, fuck even more dates or hanging out with your kids would be nice. How do I (the champion) impact my companions and the world around me? Marriage was introduced for two of our companions, and outside of the champion itself, the world seems lonely there is no couple outside of the champion which makes it seem a little unrealistic.
TLDR: More fetishes, more interactions with already established characters, impact the world, flesh out the areas around us more (Winter city is like an abandoned village for Christ's sake.) But nevertheless, I believe it will get better... I hope.
