Wish

Wishes are a new system in The Sims 3 that provides you with a wide selection of requests that keep your Sims happy as well as working towards some short and long-term goals and rewards-- similar to the Wants system in The Sims 2. Wishes come from anywhere and everywhere, based on your Sims’ traits, their job, their skills, their friends or coworkers, where they are in town, or what they might be doing. You can promise to help your Sims with a wish or you can throw it away. Satisfying these basic tasks will unlock minor rewards and increase your Sim's overall morale with a "moodlet"--a minor condition that contributes to your characters' overall mood.
