There are a lot of extras players can buy for The Sims 4: Expansion Packs, Game Packs, and Stuff Packs give players plenty of extra content to choose from. A recent addition to The Sims 4 is Game Kits. These are kind of like Stuff Packs, in that they only contain Create-a-Sim or Build and Buy items, rather than introducing anything major to the gameplay. Kits are pretty cheap, and they're a nice way to spice up the game without spending too much.
