Challenge Overview:

The core concept involves progressing through decades, with each two in-game days representing a year, starting in 1890. You can customize the starting and ending years to suit your preferences (e.g., 1890-2010 or 1890-2020). Automatic aging is disabled, and life expectancy is adjusted based on historical trends. Sims born before 1950 have shorter lifespans than those born afterward, reflecting the significant increase in life expectancy around that time.

Age Progression:

The initial life stages are consistent regardless of birth year:

  • Baby: Ages after 1 day (6 months)
  • Infant: Ages after 3 days (2 years)
  • Toddler: Ages after 8 days (6 years)
  • Child: Ages after 14 days (13 years)
  • Teen: Ages after 12 days (19 years)

Adult Age Progression:

  • Before 1950:
    • Young Adult: Ages after 26 days (32 years)
    • Adult: Ages after 36 days (50 years)
    • Elder: Dies after approximately 14 days (around 60 years)
  • After 1950:
    • Young Adult: Ages after 32 days (35 years)
    • Adult: Ages after 60 days (65 years)
    • Elder: Dies after approximately 56 days (around 90 years)

Gameplay Rules and Setup:

Begin with a single young adult Sim or a married young adult couple. Multi-generational households are permitted, reflecting common historical family structures. Clothing should accurately represent the era.

Housing is restricted: Strangerville is prohibited, Del Sol Valley is unavailable before the 1950s, and Sulani is discouraged for realism. Apartments are allowed for single Sims, but marriage necessitates a house move.

Technology usage is period-appropriate. Phones are permitted for essential gameplay functions but not for entertainment or communication until the relevant decade. Computers are similarly restricted, available only when realistically feasible for work or ordering items. Job choices should align with the historical context.

Decade-Specific Rules (Summary):
