Mods
From SI410
Mods (or modifications) are changes in the code of a video game that change the mechanics of the game.[1]
Normally, there are limitations to the abilities and content available in video games. These limitations are for a variety of reasons. Mods allow users to add clothing and objects in the game they wish the developers had included. Some actions are left out of games in accordance to the boundaries of the ESRB (Entertainment Software Rating Board) rating of the game. For example, The Sims franchise has the "Teen" rating
