"The 7th Guest" by Trilobyte. It's amazing that I still have it.
I had this bit of nostalgia because I found this site that sells old games: http://gog.com/
Of the games they sell, the only one that I still have the physical packaging of is "The 7th Guest". I don't remember the exact minimum system requirements back then, but I know I didn't have more than 4MB of RAM. The minimum system requirements now is 512MB of RAM and 2GB of disk. Computers really have advanced much.
