Yes, Call of Cthulhu enjoys excellent backward compatibility across editions due to the stability of its core percentile skill system. Most scenarios, campaigns, and setting sourcebooks work with any edition with minimal adaptation. The main differences between editions involve minor rule tweaks, skill lists, and character creation options, but the fundamental roll-under-skill-percentage mechanic has remained consistent since 1981. Converting older materials to 7th Edition typically requires only minor adjustments to skill names and percentages. This means Noble Knight's entire Call of Cthulhu inventory, from 1981 1st Edition materials through current 7th Edition releases, represents usable content for modern games. Product listings indicate edition, but most content is edition-flexible.
