I used to work as a QA Engineer @ Transmeta testing software om out CPUs to ensure x86 compatibility. My manager this operated like this. She would constantly look for old software to acquire. One of her favorite activities was dumpster diving outside of startups that had failed to pick up old copies of software on CDs and floppy disks. I remember testing a lot of Diablo 2, Tomb Raider of various versions, Star Wars Episode I Racer, and Risk (for Windows 3.0).
