Challenge Overview and Rules:

The core concept involves simulating a year with every two in-game days, starting in 1890. You can customize the starting and ending years (e.g., 1890-2010 or 1890-2020). Automatic aging must be disabled, and life expectancy is adjusted based on historical trends. Sims born before 1950 have shorter lifespans than those born after, reflecting the significant increase in life expectancy around that time.

Life Stages and Aging:

The initial life stages are consistent regardless of birth year:

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

Adult Lifespans:

  • Before 1950: Young Adult (26 days/32 years old), Adult (36 days/50 years old), Elder (dies after ~14 days/around 60 years old)
  • After 1950: Young Adult (32 days/35 years old), Adult (60 days/65 years old), Elder (dies after ~56 days/around 90 years old)

Gameplay Rules:

Begin with a single young adult Sim or a married couple. Multi-generational households are permitted, reflecting historical norms. Costumes should reflect the appropriate era. Certain locations are restricted based on historical context: Strangerville is always off-limits, Del Sol Valley is unavailable before the 1950s, and Sulani is discouraged for realism. Apartments are acceptable for single Sims, but marriage necessitates a house.

Technology use is period-specific. Phones are allowed for essential gameplay functions but not for entertainment or communication until the relevant decade. Computers are similarly restricted, only usable for necessary jobs or ordering items. Job choices should align with the era.
