CASCreate A Sim, This is where you create your Sims, you know the screen with the blue and teal background? That’s it! My favorite place in the game!

EPExpansion Pack, is a purchasable pack in addition to the base game Simmers can purchase to add a great deal of content to their games created from EA.  An example of an EP is The Sims 4: Seasons, which heavily adds content to the gameplay, build, buy, and CAS.

GPGame Pack, is like the Expansion Pack, however a bit less content.  The Game Pack itself is generally focused on an addition of a specific element of gameplay, such as The Sims 4: My Wedding Stories, expanding on Weddings for gameplay.

Mod to CAS Backgrounds.

PresetsPresets are mods that act as selectable features such as; body type, eyes, nose, eyebrows, lips, and other elements.  These presets allow for Simmers to select more than just the EA-provided features, adding more diversity and options to your game.
