Mods for SimCity 2013 are comprised of a number of file types and structures, most noteably a .package file [1] containing all of the relevant data for that mod.


Typically, a mod will be distributed in a compressed format which must be uncompressed before use. These formats may include:

Folder LocationEdit

For SimCity to load mods, the files must be placed in a specific location on the users hard drive.

Windows 7 (64 Bit)Edit

C:\Program Files (x86)\Origin Games\SimCity\SimCityData


C:\Program Files\Origin Games\SimCity\SimCityData

Mac OSXEdit



SimCity 2013 mods do not require special installation. Placing the .package mod folder in the above directory will automatically load the mod and replace existing assets or add new assets to the game.


  • SimCity loads package files in the SimCityData directory alphabetically. In order for a mod to run, it must load before the SimCity_Game_Data.package file. To ensure it loads properly, make sure the first character in your file name comes prior to 'S' in the alphabet.[2]
