Yeah, the Grim Reaper came with Livin' Large, not the base game.
He appears if a sim dies on your lot. However, you can interact with him, but you gotta be quick! Pause you game as soon as he appears. Have a living sim Plea with him. (If you are playing with only one sim, and they die, you can't do this.) Then your sim plays a game of Rock Paper Scissors.
The Reaper Wins
- Your deceased sim is returned to life! Just, as a zombie with no personality.... :/ Well, it's something, right?
- Your deceased sim stays dead.
- Your deceased sim is fully resurrected!
