Well said. What I would like to be able to do is change/tweak the % numbers. The total % would have to equal 100%, with a minimum of 1% or 5% for each listed template. "Evil eye" or "Side eyed" could also be a moodlet... as in "did that person just give me the stink-eye?" This could be a form of racially based insecurity. (Or IRL a certain amount of paranoia based on historical group behavior and personal experiences of discrimination.) Class discrimination could also be considered as well... historically the upper classes discriminate against the lower classes for instance, and the lower classes resent the upper classes. In game, this is shown as the Snob trait, but is also greatly watered down. Sims 4 also does not include Bragging nor nagging. Then again, autonomous nagging WAS an issue in The Sims (2000).
For example, the area where I live (according to the US Census) is 54% white (including all national origins), 6.6% black, 0.7% American/Alaskan Native, 20.8% Asian, 0.8% Pacific Islander, 5.3% other races. Of these, 10.5% were reported of Latino/Hispanic origin, and 10.9% affiliated themselves with 2 or more races. This is before we even go into detailed national origin break down, such as Caucasian, Arabic, Semitic, Jewish, Eastern European, Northern European, English, French, German, Portugese, Spanish or Native/Aborigines.
