SimPort allows players to send Star performers on tour to perform special shows in their friends' towns (only if you have internet and friends). They can also invite your friends to send their Sims to perform for you and customize the stage in venues with special themed backgrounds, props, lights and special effects. Players can throw objects at performers - ranging from flowers to lettuce. Choosing not to use SimPort will not change gameplay with any interactions that do not require SimPort.[3] A player can unlock backgrounds, props, and costumes for their Sim if they choose to use SimPort. Sims who visit a player's town via SimPort will default to the traits, clothes, and objects that they have locally in their game. Players can message other players while their Sims are performing in other towns. Note, there are 3 versions. The normal, limited, and Katy Perry version do not have much difference other than special venues, stages and clothing.

Starlight Shores[edit]
Starlight Shores is a new world that is included in Showtime. It is loosely based on a Californian-type urban area (Downtown Los Angeles). It has a park, a coffee house, and show venues in which sims can perform. There is also a beach with houses along the coastline. Simfests are held in Starlight Shores. These allow singers, acrobats, and magicians to compete in front of an audience.

Stages[edit]
Players will be able to set up their own stage when their magicians, acrobats and singers perform at a venue. The set up stage option appears up to 2 hours prior to a live show and will prompt buy mode’s “Props” section. Players will have a variety of items to choose from and are be able to choose a “Previously Saved” prop default, or create a brand new one. There is also the option to use the venue’s pre set prop stage. Props serve as home decor and furniture as well. Lighting effects, flames, butterflies and other effects are also available as props. When a sim has finished performing, they will get reviews on their performances. Sims can have anywhere from awesome to terrible shows. Moodlets reflect their performances.
