How to install mods (in .package format) for The Sims 3

[JoshQ]

• First you need to have the latest version available: 1.67 for steam and retail disc and 1.69 for Origin. Both are compatible with 99% of all custom content (CC) available on the net (unless said CC is defective)
• Check you have your mod folder configured correctly 
• Refresh your cache every time you install or remove a package, otherwise your game might crash
• Check for bad CC or possible conflicts using Delphy’s Dashboard

Extras:

• Rename packages that use special characters like []()-*!, underscores are fine
• The more packages you have the slower you game will load and lag will appear in-game. Combine them
• Use Nraas Mastercontroller to optimize the CAS menu so it loads faster
• Use Kure’s CASP Editor to hide the clothes, hair, shoes, accessories, etc. made by EA that you don’t plan to use, that also helps CAS to load faster
• Convert sims3pack to package with Multi-extracter
