New content is coming to The Sims 4 starting in January in the form of Game Packs. A Game Pack is much like the Stuff Packs of previous Sims games, but with additional gameplay content as well. These are the first paid content packs for the game and cost $20.
Outdoor Retreat is the first of these packs. It includes a new area called Granite Falls. new costumes such as a bear suit, new hairstyles, and new objects to interact with like a campfire and tents. Additional info is coming in January, so stay tuned!
