- Am I Able To Reflect Real Life Ages Into The Sims 3 Game?


When setting the game lifespan on Epic and adjusting every slider to the utmost right you can reach a lifespan of 1,928 days maximum for Sims to be alive (based on a Human Sims):

With the release of EP Season you are able to actually base a single simsyear with the rotation of all four season with a bare minimum of 28 simsdays is 1 simsyear (if each season are set on 7 days).

With this in mind you can now reflect the games lifespan of each ages with that of the average ages in the real world:

As you can see, with a seasonal transition of 7 simsdays each (28 simsdays = 1 simsyear), there are 3 Sliders that doesn't support adjusting these amount of ages within the Game Options. Even more when you adjust the seasonal transition with a larger number then 7.

The easiest way to get around this is opening the Options.ini file within your Documents \ Electronics Arts \ The Sims 3 user directory with NotePad (or any other texteditor) and change the values on these (use CTRL+F to search for the given names in the options.ini file cause the file is unsorted):
  • agingstagelengthbaby = 64 (initial amount) to 28
  • agingstagelengthtoddler = 150 (initial amount) to 84
  • agingstagelengthchild = 150 (initial amount) to 224
  • agingstagelengthteen = 300 (initial amount) to 168
  • agingstagelengthyoungadult = 450 (initial amount) to 336
  • agingstagelengthadult = 450 (initial amount) to 980
  • agingstagelengthelder = 364 (initial amount) to 560

Save the file and start your game. When in Game Options the numbers will be reflected in their Age life-stage, do not use the Lifespan slider to slide it to the left as it will revert the changes you've made to its own default settings.

Other interesting values to be found in Options.ini for direct altering the file:

  • Seasons
    • springlength = 7
    • falllength = 7
    • summerlength = 7
    • winterlength = 7

Pets ages aren't listed in the game options, it will calculate in the background their set lifespan ages based of what a gamer has set on Human Sims. If this is something you want to have control over, here are some example given and where in the options.ini file it can be altered:

- Is There A Mod That Can Hold Different Lifespans On Certain Worlds?


Unfortunately there isn't one. The Lifespan settings are held in the Options.ini file within your Sims 3 user directory and is loaded when you start your game. Once you are in your game you are able to adjust the sliders of the lifespan manually of each ages in the Game Options. As far as I know these files aren't easily modded.

Although not something special, but can come in handy in these particular situations:
  • Start game Sunset Valley set your Lifespan-settings in the game options. Save game and exit. Make a copy of your options.ini file in your user directory and rename it to SVOptions.bak and place this somewhere else outside your Sims 3 user directory.
  • Start game Roaring Heights set your Lifespan-settings in the game options. Save and exit. Make a copy of options.ini file in your user directory and rename it to RHOptions.bak and place this somewhere else outside your Sims 3 user directory.
  • Repeat process for any other worlds you like to play with different Lifespan.

Note: Make sure you give the file name something you can relate to your SavedGame within your Saves folder, so its easy recognizable which "options.ini" belongs to which SavedGame files.

Whenever you decide to play a world go to your location where you saved those files and copy the one *options.bak related to the world you like to play, rename it back to Options.ini and place it inside your Sims 3 user directory, when ask to overwrite do so.

This beats adjusting the lifespan slider of each Ages manually within the Game Options in each session of each world you like to play. You will need to exit the game completely every time, when you decide to play a different world.
