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, with the progress towards completion being tracked independently from the internet connection. The achievement of the player's online friends can be viewed by the player. Likewise, the player's achievement can be looked by others.
