There is no definitive answer to this question as opinions vary greatly. Some people may feel that Sims still provide a great experience after all the changes made to them since the game was first released, while others may feel that they are only popular because of the popularity of the Simulant class. Many people will never find a use for a Simulant, and many people feel that they are unnecessary and a hindrance to the experience. Ultimately, it is up to the individual to decide whether they feel that Sims are necessary or not.
