Career Highlights: Doom ( 1993)

Resume: As the designer of id's Doom, Romero has arguably done more than anyone to establish the PC as a truly all-round games machine. No longer is the PC considered a home for worthy flight sims o r adventure games.

Doom was written around a breakthrough 3D graphics engine and, using first-person perspective, it placed players in as action-packed a combat game as has graced any console. It's impossible to calculate how many people have played Doom, as it was available exclusively on shareware long before it came to retail and is almost certainly the most pirated game of all time.

Retail versions are also available on PlayStation, Jaguar, SNES, Mac (Doom 2), and 32X. Ultra 64, 3DO, and Saturn versions are currently in development. Back on the PC there's already been Doom 2 ( 1994) released at retail. A third and similar game in the series, Raven's Hexen, is available in shops. But the real excitement is building up for next year's release, Quake, which will introduce an all-new id graphics engine.
