The core concept is simple: every two in-game days represent a new year, starting in 1890. You can, however, adjust the starting and ending years to suit your preference. This means 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 (All Sims):

  • 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)

You begin with a single young adult Sim (or a married couple), potentially including parents for a multi-generational household. Strive for historically accurate attire for each decade. Housing is restricted: Strangerville is off-limits, Del Sol Valley is unavailable before the 1950s, and Sulani is discouraged for realism. Apartments are acceptable for single Sims, but marriage requires a house.

Technology usage is period-specific. Phones are permitted for gameplay necessities but not for entertainment or communication until the appropriate decade. The same applies to computers. Job choices should reflect the available professions of each era.
