boolProp testingCheatsEnabled true: This cheat was used in the making and programming of The Sims 2 to test objects and sims. It allows you to click on a sim and change their aspiration or aspiration bar, give them an illness, kill them, add sims to the family without asking them to move in or marrying them, and tons of other stuff. You press shift and then click on something and it shows you the available options. The objects with the most interactions are the mailbox and sims. For most objects the only option when you press shirt and click is force error (never click this!) Remember this was supposed to be used for testing and programming and some things can really mess up your game, so use it at your own risk.
