The One Thing in TS4 I'm Not Disappointed About.

Ambient sounds! I love hearing the wind blowing through the trees, rain, thunder, lightening, waves crashing on the shore, waterfalls, birds calling, coyotes howling, bicycles, Sixam plant when it snaps it's jaws, how the sound changes when Sims are walking depending on the terrain, the paddleboat whistle, trains going by, fish jumping, oh man, I could go on forever listing all the ambient sounds in this game. I love it! <3
