Gravestone

An urn or gravestone appears on the lot when a Sim dies. An urn can be placed on the floor or on tables and counters. A gravestone can be placed on the ground outside. Sims can "Mourn" over graves or urns. With Nightlife, they can be moved to a community lot.

the Sims 2

if a Sim had a platinum status when he/she died of old age, a gold gravestone/urn will appear with the dead Sim's aspiration symbol on it. If a Sim had a disturbed or troubled life, where few wants were fulfilled or many bad things happened, this will result in the average, gray gravestone/urn.

When there is a gravestone on the lot, sims have the option to "Move grave(s)" this moves the grave to a community lot of your choice. it is a good idea to make a cemetery if you plan to have one, but there is "Gothier green lawns" found Downtown next to the House of Fallen Trees.

In the sims 2 pets, pets also have the gray gravestone/urn, but the master of the pet will get a special memory.

the Sims 3

In The Sims 3, the plaque on the gravestone shows how they died:

• Lightning Bolt: Electrocution
• Hand sticking out of a pool: Drowning
• Flame: Fire
• Hourglass: Old Age
• Fork and Knife making an "X": Starvation
• Sphinx: Mummy curse

There are at least 3 different types of graves in the graveyard that comes with the game, a flat plaque like one, a tall obelisk type and another similar to those in The Sims 2. A Sim can obtain these different gravestones by:

Small Plaque

dying without completing lifetime wish;

Medium Grave

dying after completing lifetime wish and having earned 50,000 - 150,000 lifetime happiness points;

dying after completing Lifetime wish and have earned 150,000 or more Lifetime Happiness points.

Large Tombstone

The player has the option of whether to keep the grave on the Sim's home lot or to put it into Cemetery.
