World Building Tips/ Don't get bored

Hey everyone, 

Okay, TL;DR I've been playing with my sims legacy generation for a while now and I'm trying to develop the lore around my vampire/werewolf occults. I don’t have much storage left on my **bleep**ty laptop so probably can’t install any mods. 

so far I’ve created a few little vampire covens and werewolf packs using the get together club system. And when I was playing with my Gen 2 vampire sim I obviously had them date Caleb and I kinda played about with developing an occult council (putting all the occults into one club and kinda having them debate rules for occults and stuff). 

im currently playing a vampire werewolf love story which has been fun, they now have 3 children together and I really want to give each of the children a bit of a fleshed out story. So if anyone has any ideas or gameplay tips because I’m so passionate about this save file atm and I don’t want to get bored!
