In 1995, "Next Generation" said it was "The most talked about PC game ever – and with good reason. Running on a 486 machine (essential for maximum effect), "Doom" took PC graphics to a totally new level of speed, detail, and realism, and provided a genuinely scary degree of immersion in the gameworld."
