The Strong National Museum of Play's International Center for the History of Electronic Games has acquired another great piece of video game history. Joel Billings, founder of Strategic Simulations, Inc. has donated a collection including company documents, source code, and games to the museum covering the period from the company's 1979 founding until its sale to Mindscape in 1994. SSI is best remembered for its "gold box" series of games based on the Advanced Dungeons & Dragons franchise, which kicked off in 1988 with the release of Pool of Radiance. Over the last several years, the museum has racked up some important collections, including one from Microsoft covering Windows and Xbox products, and a massive collection of Japanese video games.
