Things You'll Need
Instructions
Start "The Sims 3" and enter the household where you want to influence the shape of a Sim's future tombstone.
Click that particular Sim so she's the active Sim, and review her"wants" in the center of the game control panel along the bottom of the screen.
Hover your mouse cursor of the want icons to see what you need to do to satisfy them. Every want you satisfy generates happiness points that lead to lifetime rewards.
Click objects, people and buildings in the game to issue commands that fulfill your Sim's wants. The more wants you fulfill, the more points you generate. Accumulate more than 150,000 points and your Sim will receive the largest tombstone possible upon his death.
Click the "Lifetime Rewards" tab on the right side of the game console to view how many points your Sim has accumulated.
Click the "Simology" tab to check your Sim's age. Barring any unfortunate accidents such as drowning, fire or electrocution, your Sim will pass away when he reaches a ripe old age.
Hover your mouse over your Sim's lifespan graphic to see how many days must pass before he becomes an elder if he isn't one already. After he's an elder, hover over this area again to see approximately how many days he has left in his lifespan. Some Sims exceed their lifespan by a few days, but most expire before the last day.
Continue to play your game until the Grim Reaper appears, indicating a Sim has died. After the Grim Reaper leaves, look for a tombstone in the area where the death occurred.
