Maxis "Get Cool Stuff" Archive

Official Maxis content not included in Legacy Collection – restored and ready to install

Between 2000 and 2003, Maxis released free official objects, skins, and houses through the "Get Cool Stuff" section on thesims.com. Most of this was not bundled into Legacy Collection – either because licenses expired (branded objects like the McDonald's cart, Pepsi machine, and Intel computer) or it was simply not included. The community has archived all of it.

RECOMMENDED Legacy-Compatible Archive (alon-abadi)
All known Maxis "Get Cool Stuff" content packaged specifically for Legacy Collection. Files are pre-extracted and organised by destination folder – no old .exe installers to wrestle with. Includes branded objects, promotional skins, NPC templates, and official houses.

How to install
Download the archive, open the folder for each content type, and copy the files into the matching folder in your game install. The archive mirrors the game's folder structure – objects go in Downloads\, skins in GameData\Skins\, and so on. Each subfolder has a readme explaining where the files go.

Quality of Life

Mods to balance the difficulty curve of the Sims 1

โš ๏ธ Install paths below use the Steam folder name. If you bought the game on the EA App, replace The Sims Legacy Collection with The Sims Legacy in every path. Subfolder names (Downloads, GameData, etc.) are the same on both platforms. See Installing Mods for your full path.
โ„น๏ธ Shared .iff filenames. Several mods share the same .iff filename (e.g. SocialInteractions.iff). You can only have one of each active at a time – read each mod's readme and pick the one you want.

โญ Notable mention – No Pets Allowed Sign: A built-in base game object in Buy Mode → Decorative → Misc (requires Unleashed). Not a mod, but easy to overlook. Strays (loose cats and dogs) wander onto lots and urinate outdoors, knock over bins, and leave mess, all of which tanks the outdoor Room score and makes your Sims uncomfortable and unhappy every time they step outside. Placing this sign anywhere on the lot keeps strays off it permanently – no mod, no hack, no side effects. One of the most useful objects in the whole base game and almost nobody knows it exists.
