In Sims 3 we were allowed to customize the lifespans for our Sims by either using the game options UI or editing the options.ini file.
In Sims 4 we cannot easily modified the 3 lifespan settings: Short, Normal, and Long. In fact, it is not even easy to find out what the age settings details are.
I found out what these fixed lifespan settings are at Carl’s The Sims 3 Guide then later found them by digging around in the XML gotten using Scumbumbo’s XML Extractor for The Sims 4. The settings are located in sims.aging.aging_tuning
I did at one have a mod here for download that modified the lifespans based on the tables below, but I have since found and easier way to customize the lifespans – read on…
(This is what the default settings were before toddlers were added)
|Long||3||52||52||80||80||Vary by Sim|
|Normal||3||13||13||20||20||Vary by Sim|
|Short||3||7||7||10||10||Vary by Sim|
As I have read on a number of forums, many players do not like these lifespan settings and because of that will either play with aging off or they will manually age-up all the Sims.
To me these numbers do not make any sense. When playing TS3, I prefer a 300+ sim day lifespan in which 4 sim days = 1 year. Sometimes I play a shorter version of this in which 2 sim days = 1 year and the lifespan is 150+ sim days. The plus sign (+) represents the fact that Sim elders do not die immediately on the last day of the lifespan. In both cases, the lifespans represent 75+ real-time years. For a discussion of why I prefer a 300+ sim day lifespan based on the length of Sim’s pregnancy duration, see this page.
After some research, I discovered that I could easily create a TS4 mod that allowed me to play with the lifespan settings that I was accustomed to. However, you no longer my mod because MC Command Center makes this customization of the Sim’s lifespan much easier.
NOTE: I have removed the mod that I had here for download for two reasons: 1) it did not include toddlers and 2) it conflicted with MC Command Center.
In fact, instead of using my mod I suggest using Deaderpool’s MC Command Center to do custom settings, because even if I were to update my mod it would still conflict with MC Command Center. If you have the MC Command Center mod installed, I find the easiest thing to do is to open the mc-settings.cfg in a text editor such as notepad and at the very top of the file you will see the lifespan settings. This file will be in your under your mods folder wherever you installed the mod (for example, \Electronic Arts\The Sims 4\Mods\MC).
Here is a 300-day lifespan (4sd=1yr)
Here is a 150-day lifespan (2sd=1yr)
Again for a discussion of why I prefer a 300+ sim day lifespan based on the length of Sim’s pregnancy duration, see this page.
