One mod I would recommend would is this autosave mod for The Sims 2.
Creates a dialog that pops up asking if you wish to save your game. If so the game will automatically be saved, If not the game will carry on with out saving. By default the auto save dialog will appear every 24 sim hours, Though the saving frequency can be changed with the Auto Save Game Manipulator. Their are two interactions on the Auto Save Game Manipulator. The "Change Auto Save Frequency" interaction will allow the you to change how often the auto save dialog appears, Right now you can make the dialog appear every sim hour to every 100 sim hours(uses the grocery dialog). The second interaction "View Current Auto Save Frequency" will allow you to view how often the auto save dialog appears.
