As “The Sims” evolved, so did Simlish. Instead of one-syllable utterances, words now have fairly complex structures, and there’s a larger emotional range. Originally, Sims put their hands to their faces to laugh and performed an identical gesture to cry. By “Sims 4,” which debuted in 2014, they quietly wept over more-trivial issues but visibly sobbed when somebody died. The whole game developed an emotional IQ.
