Can't remember a game where their is a normal human that ends up in a version of earth ruled by a powerful succubus and her I believe 8 children and when you enter the world you meat a half succubus and live in her mansion and can become several different races by eating the relevant food .you can also learn magic and take slaves / have a polygamous relationship and your quest is to weaken the succubuses power and rule the world / free the world / return the world (I think that's all the endings
)
