I love my vamps. I have a story of three immortal sisters that drive my game play. 1 Sister is a witch - she runs a magic school. 1 sister is a mermaid and as such the mother of all mermaids. 1 is a vamp. In my game she is and the mother of all vampires and vamp queen.
I play my own version of the Vampire Family Legacy. Vamps “can’t” have kids in my game. Ultimately she is growing her vampire clans. She has a human sim that lives in the clan as her personal plasma source. The human sim acts as a way to “mark the generations that pass.” She can only turn 1 sim at a time. That new sim has to reach level 3 vamp/Prime before she can turn the next one. She trains them all up. They have to master certain powers before they go. Only certain sims are bestowed the ability to turn others. They all work on 1 skill at a time and work to master it before moving on.
I do have some in the clan on permanent hibernation depending on what I’m focusing on. I play a lot with interpersonal drama.
Once she has 3 vamps at prime status they can move out and start their own clan in a town outside Forgotten Hollow. She gets cranky and punishes vamps who haven’t been approved to turn someone - there have been a few sunlight deaths.
I’ve had sims run off to be good vamps that she’s hunted endlessly. Others that are werewolf sympathisers which she feuds. Other vamps that I’ve made really evil. Drinking the town dry, putting sims in prisons in the basement to feed on. She goes and fights them. If she wins… they come back to the main clan house…. And are subjected to the sun.
