Game over

In The Sims series, a game over occurs when there are no more playable Sims in a household. This can be caused by death, or when there are only children living after adults or teens die.

The Sims
In the PC version of The Sims, there is no game over screen and the lot remains playable. All modes will continue to be available indefinitely. The player will not be able to return to this state if they save and exit the lot; should they attempt to return, they will either be told that nobody lives on the lot, or be taken to build and buy mode—sans live mode—if Unleashed is installed.

In The Sims for console, if a Sim dies, gets fired, leaves for good after losing a fight, or runs out of money in Get a Life mode, a game over message will appear and the player will be returned to the main menu.

The Sims 2
The Sims 2 introduced a game over screen featuring various dialogues of the Grim Reaper known as The Finale. After the last Sim dies, time is paused and the player loses control of live mode. The lot is still playable in build and buy mode, and the remaining funds the household had are still usable.

The Sims 3
The Sims 3 has a game over screen known as The End.... Clicking on the checkmark brings the player to the neighborhood view.

The Sims 4
The Sims 4 lets the player have two options after the last Sim dies. The player can save and continue to play with the world, or return to the main menu without saving.
