1.) Need Freak by Boiling Oil
Has seven various styles & functions but when set will automatically prevent a Sims needs from falling below a certain check point so you never have to worry.
2.) More Fun by Cyjon
Lowers motive thresholds so sims will stick with fun activities longer. This mod prevents most fun activities from being considered lower priority than other commands. In the unmodified game giving a command will break sims out of fun actions like watching TV, but with this mod it won’t. This takes a little getting used to, especially if you’ve been playing for a long time and unconsciously expect sims to stop having fun and defer to other commands.
3.) Self Preservation by Cyjon
Sims will be less stupid about taking care of needs, emphasizing hunger over bladder or energy.
