Challenge Overview and Rules:

The challenge spans from 1890 to 2010 (or 2020, depending on your preference), with each two in-game days representing a year. Automatic aging is disabled, and lifespan is adjusted based on historical life expectancy: Sims born before 1950 have shorter lifespans than those born after. Begin with a single young adult Sim or a married couple. Parents may also be included in the household, reflecting multi-generational living common in earlier eras. Clothing and household items should reflect the appropriate decade. Certain locations (Strangerville, Del Sol Valley before the 1950s, and Sulani) are restricted to enhance realism. Technology use is limited to its historical availability; phones are permitted for gameplay necessities but not for entertainment or communication until the relevant decade. Job choices should align with the historical period.
