The Sims: SuperstarEdit
The obsessed fan is an NPC introduced in The Sims: Superstar. Celebrity Sims with three or more fame stars who do not pay enough attention to their fans attract an obsessed fan. Obsessed fans stalk the Sim at home and any community lot. They will dig through the Sim's garbage can, and eventually start sneaking into the Sim's home to steal awards. Buildings can be protected with the "Zeddy-Lock Celebrity Security Door," which prevents the obsessed fan and non-famous Sims from passing through it.
A Sim will continue to be stalked by the obsessed fan until they improve their relationships with their fans. However, there are ways to deter or temporarily get rid of the fan. Celebrity Sims can berate the obsessed fan and ask him to leave, but he will always eventually reappear. The butler (and ironically, the Tragic Clown ) will also fend him off. If a Sim is on a Studio Town or Vacation Island lot, the Sim can ask Lana or Kana, respectively, to shoo the fan. Another method of ridding the Obsessed Fan is by using a Voodoo doll on him, and if there is a ghost on a lot, will flee in terror.
The obsessed fan often leaves black roses on a Sim's home lot. In The Sims: Makin' Magic, these roses can be used to produce the Price of Fame charm. If the charm backfires, five obsessed fans appear on the lot. Magical Sims can also use the Toadification spell to turn an obsessed fan into a toad, though the effect is temporary.
The Sims 3: Late NightEdit
In The Sims 3: Late Night, when a Sim plays the guitar, fans will come and watch. The relationship level between the performer and the fan and the fun level continuously rise until either stops the interaction.
The Sims 4: Get FamousEdit
Celebrities who reach a fame level of two stars or higher will start getting noticed by fans in public, who will follow them around excitedly. Celebrities can sign autographs, take pictures with them and hug them.
Frequent interactions with fans may result in celebrities gaining the A Stan or "Fan" Mail fame quirks. The A Stan quirk causes a celebrity Sim to attract the attention of an obsessed fan, who will follow them around everywhere (even to their home). Obsessed fans who are invited into a celebrity's home may steal objects. With the "Fan" Mail quirk, celebrities will frequently receive collectables and garbage in the mail.
