Opera Soft was one the most prolific Spanish computer game developers of the so-called Golden Age of Spanish software of the 1980s. It released many games for the Spectrum computers in the mid-1980s, but its games were not as popular on the PC. Founded in 1987, the company obtained success with its premiere title 'Livingstone, supongo' (Dr. Livingstone, I Presume), based on the famous 19th-century explorer Dr. Livingstone. Nevertheless, their most important title is probably La Abadía del Crimen (The Abbey of Crime), based on Umberto Eco's best-seller The Name of the Rose.
Like many other Spanish software companies of the time, Opera Soft did not adapt to the generational change and went out of business in the early 1990s with the emergence of 16-bit video games.
