The one strange exception is The Sims. Some of the radio stations in-game feature Sims talking, but since your virtual world citizens speak Simlish, your ears don't really pick it up as language—because really, it isn't. The soundtrack to The Sims is incredibly conducive to efficiency, probably because you're supposed to play the game for hours doing tasks that are arguably kind of boring. You draw walls and place furniture, you tell your Sims to go to the bathroom, then you wait as they slowly eat the lasagna they made for dinner. Just try playing The Sims in silence. It's kind of dull. But with that cheerful music in the background, you're compelled to keep going.
