Steam World Mod

Steam World Mod transforms RimWorld into a 19th century (1800s) setting by restricting advanced technologies and introducing period-appropriate systems. Designed as a companion to the Rimworld Westernization Project, it creates a more immersive low-tech experience focused on steam-era progression.
