We used DOOM demo mode running on an FPGA as one of the standard tests during the design of one of our processors .... and one of the obscure bugs that it found was always referred to as the "Doom bug" (a previous design via a similar process had encoutnered "the Gimp bug").
Also, a few years earlier when a group had been spun-off to develop "multimedia processors" and the marketeers had decided that they all needed Apple Newton's to understand the "mobile computing market" then the engineers decided in repsonse that they needed to understand the "multimedia gaming market" so installed a Doom network in the lunch room!
