Achievement

Achievement is a system introduced in The Sims 3 and later reintroduced in The Sims 4.

The Sims 3
The Sims 3 has an achievement feature available to users who have logged into TheSims3.com in-game, and are awarded and stored on their user profile. Some achievements have an expiration date and can only be unlocked during certain periods of time. Badges can be earned by completing an achievement; progress is tracked offline, but the player must have an Internet connection for achievements and badges to be awarded. Achievements are visible to other friends online.
