A new trailer from The Sims 4 shows how you can influence the emotions of your sims, just as if it was real life (and if you were a horrible manipulative person). The clip is suitably Sims odd, with one example showing a sim staying "focused" by cheating at chess. This is not the only example of a Vulcan's understanding of this topic, as besides actual emotions, they include states like playfulness, boredom, energized, dazed, flirty, uncomfortable, and more. No Sims remained unharmed in the making of this video.
