What is a Mod? A mod allows you to access features and options in the Sims 3 game that you normally wouldn’t have access to.
It is actually VERY easy to add mods to your game. I also am willing to bet that you tried to download some things that are called Mods – and received an error message. You have also downloaded items and people from the Exchange.
If you are like me you have played the Sims since their creation.
