Seeing I have finally fine-tuned the aging system in Sullivan to be exactly as I like it (heavily based on the aging system at Lakeside Heights), I thought I would revise my shamefully outdated aging post. If you still want to read that one, it's here. I think most long-term readers will have already picked up what I'm doing as we've gone along. With my StatCounter though, I noticed I'm getting a lot of page views on that old aging post and I think some readers out there might be confused!
My rounds represent two years of real-life time, so Sims get two years older each round. I track time by months. Each month features 1 or 2 regular family updates. Some months will also feature a birthday update (which occur exactly one year after birth for babies aging to toddler but only in January for all other age stages). University updates for students living on campus are always in March. Occasionally, I might have a special mini-update for a wedding or another special event I might want to cover outside of the confines of a regular update. Those could occur in any month.
My age stages have been adjusted from the default to make this system work better for me.
The baby stage lasts just one day, to represent one year.
Toddlers have four days, representing ages 1-4.
Children have 7 days, representing ages 5-11. Round 21 will be the first time I age Sims to teen at 12, rather than 13 as I've done previously. My high school is Grades 7-12 and I started Grade 7 at 12, so it's just what makes sense to me.
Teens have 6 days, representing ages 12-17. 18 as "adult" makes sense to me, seeing that's generally the age of majority, at least in Australia (where I live).
At 18, Sims will either enter the workforce or go to college. At 21, if they went to college, they'll complete their final year and 22 will mark their first round back in the main hood.
The adult stage lasts for 44 days if the Sim doesn't go to college (representing ages 18-61) and 40 days if they do go to college (representing ages 22-61). Why 61? I don't know. I decided my first-day elders were 62 so long ago that I can't remember. It made sense to me at the time though. Becoming an elder at 54 didn't - my parents are older than that and they don't look anything like the elders in TS2.
I have edited my elder stage in SimPE so that some Sims might live until their mid 60s and some might go well into their 90s (I've forgotten the exact parameters I set, but I'll update this if I ever remember to check!) I also removed the possibility of getting bonus days for high aspiration. All my Sims seem to end up perma-platinum by middle age so all my Sims would get the "bonus" days anyway.
