I was working on a ship back in '94 or so when I got my hands on a copy of Doom.
It took about a week until the IT guy and I were blasting away at each other, another for the bridge to get on board during their down times . After that the black gang and anybody else with access to a computer was fighting the good fight whenever they could. Happy, happy days and nights.
Agree with the above comment -- it was the sound and music that really iced the cake.
