Game Help:What are Hacks?
Hacks (also called mods) are custom content files that change something about the way the game works. An individual hack may change something incredibly small (like allowing you to cancel the action when a sim is trying to make the bed), or may change lots of things in your game (like adding teen pregnancy, infertility, miscarriage, etc.). The more things a hack changes, the more likely it is to have a conflict, but even the smallest of hacks potentially can conflict or be incompatible.
