The Van Gould family is a family who debuts in The Sims 3: Supernatural and live in Moonlight Falls. It consits of Ayden Van Gould and his two teenaged children, Tristan and Emelie. Every member of the family are vampires and they have a feud with the Wolff family over who founded Moonlight Falls, everyone apart from Emelie who is in a relationship with Waylon Wolff.
Ayden's son, Tristan, is based on Edward Cullen from the Twilight series. Not only that, the feuding of werewolves vs vampires is similar to the Twilight series.
The Wolff and the Van Gould family are very similar to that of the Capp and the Monty family from The Sims 2, both are families who are feuding and both have a member of the family who rebels against the feuding by dating a member from the other family.
