I always loved how the vampires were designed to be so in tune with everything else in the pack. Their needs would rapidly drop and they would die if awake during the day (indoors or not, a touch I personally prefer) but then as a trade off their motives would completely freeze at night, meaning they were free to do anything and everything they wanted downtown.
I really miss that poker table too, and all the animations that came with it, or pretty much all the animations across the pack in general. The way Sims would act when sat at the bar, the conversations over a meal, the ridiculous dancing from outgoing Sims that would make every other Sim laugh, it had so much life to it.
