-Making all of my sims look the same
-Giving my sims the same traits. Even with the trait randomizer I usually randomize until I get traits that I want. The most I've branched out was having an unflirty sim and even then I don't consider that a bad trait like some others do. She just wasn't focused on romance like all my other sims
-Making all of my sims find "the one" as soon as possible and never having them date anyone else. I love romance in this game way too much for someone who isn't very romantic irl.
-Never having my sims socialize. Usually their only friends end up being their siblings and their significant others.
-Turning autonomy off and micromanaging everyone
