Libraries like Avsim.com and Flightsim.com became the central repositories, hosting hundreds of thousands of files, each with user reviews and version histories. The unwritten social contract was strict: no payware-level restrictions, no asset theft, and full credit to original authors. This honor system fostered collaboration; a talented texture artist might team up with a modeler and a flight dynamics engineer to release a complete package under a shared virtual “studio” name. Forums buzzed with support threads, tutorials, and requests, creating a self-sustaining educational environment where newcomers learned by modifying the work of veterans.
