Ask a random gamer, PC owner or not, for opinions of Doom and you'll be lucky if you get one. Ask them for memories and you'll get a dozen. Even those who've never shot the barrel and turned the imp into pixel mush remember it as if they had, its greatness written in lost man-hours, failed exams, smuggled serial cables and soiled pyjamas. Little wonder, then, that creator id Software chose to apply that legendary brand, almost a decade later, to a game that arguably didn't need it.
