Both wonderful ideas, but the hareem doesn't really appeal at the moment. I want some story and not just a string of sexual encounters.
The submissive would work, but the other player would have to be very strong willed and very clever, otherwise it just ends in stalemate.
Alas, many have tried, but few have managed to find that key to unlock my submissive side.
"Challanging as in difficult for your character? Challanging intellectually? Challanging as in morally?"
All.....though morally there are few things that I wouldn't do and just wouldn't find them a challenge, but abhorant.
As for genre? I comfortably play any age any era and any fantacy setting.
Save me from the odd socks of doom!
