Extracting the files from the zipped folder (optional, not applicable for some mods).Installing mods may sound simple, but it’s composed of a few steps and can take a while, depending on the size of the files you’re downloading.

The great news is that mods aren’t complicated to install, but you still need to pay attention to some detail to get the most out of them.

However, members of the online Sims community have spent countless hours developing content to enrich and enhance the game and bring it to new heights. Many Sims 4 players enjoy how the game looks and works as-is.
