The Gift Reloaded
I enjoy this one because its one of the few games dealing with Mind Control power fantasy done right, disappointed it was abandoned right in the middle of a cliffhanger.
Our Fate - A New Family
Besides being a typical Father/Daughter incest game, what caught my attention was the writing and the options on how you interact with the daughter, whether as a loving caring father or a manipulative scumbag. There is also the option on what route to take on handling the daughter, make her your romantic partner, your submissive slut or corrupted whore. Still crossing my fingers this game would come back.
Honorable Mention:
The Tyrant
If you like incest, corruption, maledom and NTR, then this is the game for you. You have the choice of going for a romance path or a dark corruption path when interacting with your mother, sisters and other female characters. While I don't like NTR, you have the option to avoid it and make the girls yours only. Initially this game was abandoned but came back from the dead after 1-2 years of no update.
