Oculus Rift founder Palmer Luckey said in a Wired interview that this episode inspired him to work on his virtual reality device.
The building and exterior used for the software company, Marathon Images, is the same building and exterior used as the location of the Bio-Dome in Bio-Dome (1996).
The exterior of Hastings Rock in the game is remarkably similar to the castle in The Wind Around the Tower (1992).
The exterior of the Virtual Images building was used in Star Trek Next Generation as Star Fleet Academy. Perhaps that explains the reference to "Valley of the Klingons".
