The Sims 3 Showtime allows players to connect and share with their friends and fellow fans of The Sims without ever leaving the game. Players will venture into a new world and live the dream as singers, acrobats, magicians and DJs. Using the all-new SimPort feature, players can send their Sim into a friend's game to perform in their world, book gigs in their friends' town, go on tour, and be reviewed. Along the way, players can earn rewards for achieving goals and accomplishing special challenges that can be tracked and shared via in-game social wall posts. Players have the opportunity to post their Sims' successes, share gameplay techniques, create wishlists and send gifts, search for new friends and share memories through their in-game news feeds and as e-cards.

Players who enjoy building can customise their Sims' stages using props and special effects to create unique venues such as a swanky concert hall, a massive stadium or an indie club. How the stage is built will directly influence a player's Sim's performance and career progression. For players who love a challenge, they can earn in-game rewards and accomplish goals such as performing a legendary show in a high-level venue. For players who enjoy experimenting, an endless amount of gameplay opportunities and choices within the game provide a vast array of situations for cause-and-effect play and hilarity to ensue.
