New Living: Apartments & Penthouses. That kind of communal living is common in cities, and it brings opportunities to add fun extra experiences for your Sims too.
New Events: Festivals bring in so many new fun situations for your Sims, from the curry challenge at the Spice Festival, selling their creations at the Flea Market, or picking up some merch at Geekcon. Excited? You can find out all about these, along with the Romance Festival and Humor & Hijinks Festival, by clicking on their names.
New Possibilities: 3 new careers: Social Media, Critic and Political. These all work a little differently to traditional careers as you can either send your Sim off by themselves, or you can head out on assignment with them in San Myshuno.
New Activities: Karaoke, Video Games & Basketball! Get your Sim working on the new singing skill, their fitness or just relax with some gaming!
