@Sharonia - Such a cool thread! For me, my vampire gameplay is where I can be super creative, thinking very far outside of the box as it relates to storylines and play a little bit dark. I have a rotational vampire save, and they're the same vampire family I've been playing since Vampire GP was released. As it relates to ages, I kind of have my own vampire lore, so I see some of my older vampires as centuries years old.
My vampire gameplay started with one of my favorite Sims who was born in game, when TS4 first came out, Kelsi Lothario (granddaughter of Don Lothario). She was captured by Vlad, and held in his basement, eventually him turning her vampire against her will. She met another vampire, Ambrose Gautier, who was also one of Vlad's slaves, helped Kelsi adjust to being a vampire. They eventually fell in love and came up with this master plan to takeover, & kill Vlad, which they did. The Gautier's are now the top family in Forgotten Hollow. So the story is essentially about the Gautier Legacy and power & the obstacles that Ambrose/Kelsi have faced, not only to protect their families legacy but also the ups and downs in their relationship/marriage. I do play rotational, so each of their kids has their own storyline as well.
Since they're vampires, I always say that anything goes. There's no storyline that's 'too crazy' or 'too out there'. I always try to use different strengths and weaknesses and experiment with that. I try to pick things that fit the character. But I love vampire gameplay. I like the duels, etc.
I'll show you one of my favorite vampires who was born in game. Ambrose was abducted by aliens and had a baby, that I named Aspen. I think alien/vampire hybrids are broken. But by far, Aspen is the most powerful vampire that I have. She's full vampire with alien powers. & I think she just looks totally rad.

I'm a huge X-Men fan, so Aspen reminds me of Nightcrawler. I didn't plan for Ambrose to get pregnant lol, it just happened in game and I flowed with it. So much has happened in this Save, all these unexpected events which just makes vampires just that much more enjoyable.
Good luck to you on your vampire play. There's a thread called Bare Your Fangs, that I will direct you to, if you're interesting in getting some vampire inspiration. Happy Simming
