Understanding the Rules

The core concept: Every two in-game days represent a new year, beginning in 1890. You can adjust the starting and ending years to personalize your challenge. For instance, days one and two are 1890, days three and four are 1891, and so on, typically concluding in 2010 or 2020. With the Blast from the Past event underway, it's the perfect time to embark on this historical journey.

Remember to disable automatic aging and utilize the following life expectancy guidelines. Life expectancy significantly changed around 1950, so Sims are categorized into "born before 1950" and "born after 1950" to reflect this historical shift.

Life Stages (Both Categories):

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

Adult Sims Born Before 1950:

  • Young Adult: Ages after 26 days (32 years old)
  • Adult: Ages after 36 days (50 years old)
  • Elder: Dies after approximately 14 days (around 60 years old)

Adult Sims Born After 1950:

  • Young Adult: Ages after 32 days (35 years old)
  • Adult: Ages after 60 days (65 years old)
  • Elder: Dies after approximately 56 days (around 90 years old)

Challenge Setup: Begin with a single young adult Sim (or a married couple), optionally including their parents for a multi-generational household. Strive for historically accurate clothing choices for each decade. Housing is restricted: Strangerville and Del Sol Valley are unavailable until the 1950s, and Sulani is generally excluded for realism. Apartments are acceptable for single Sims, but marriage necessitates a house.

Technology Restrictions: Phones are permitted for essential gameplay functions but not for entertainment or communication until appropriate for the decade. The same applies to computers, which are necessary for certain jobs and online ordering. Job choices should reflect the era's available occupations.
