Players are responsible for the mods they download, so only download mods from reliable sources. Mods are user-created and not a part of the official Sims 4 game. Script mods tend to be riskier since there’s more room for error due to the longer code. However, script mods replace existing code with brand new code from beginning to end.
Most mods alter the existing code for the Sims 4. When the creator becomes aware of the issue, they can update the mod to fix the glitch and even add new content. However, being created by amateur players, some mods will have problems, especially new mods by new creators. The best mods work just as well as official Sims 4 expansion packs. You must download mods from a third-party, while you can download expansion packs directly from the EA website or app. Mods are different from official Sims 4 expansion packs as they are made by Sims 4 players instead of EA. Many users think of mods as free expansion packs, but there are distinct differences between the two. Finally, mods can also add new experiences and storylines for your sim to enjoy.
Other mods make gameplay more convenient and efficient. Some mods add new features in Create a Sim (CAS) and Build Mode. Mods are files of additional content you can download for the Sims 4.
