Why don’t you make a game where the Mc male or female must have children the children are your new life. Depending on the other parents stats or abilities if any are passed on. Will you be able to breed the best. What type of abilities magic or fighter, hunter or gather. Sexual skills? There’s many possibilities with different races and in between the towns/cities you will have to fight monsters/undead for food/resources. To throw a twist in it you will have to protect/support with food/resources the female until the child/your new life is born. Be careful or you may become a monster yourself if you breed with too many races trying to become the strongest. Then the town folks may hunt you. Well hope this will give you something to think about even if you don’t use it. Take Care I’m looking forward to your next story
