It was in my PC Mag, and I was reading it on the throne, so no. I can't give you a link but PC Magazine online should have the stories from the latest mag.
Best.
EDIT:
From the Mag.....
Innovators: Tim Sweeney
Kids spending too much time playing video games? That's what Tim Sweeney's parents thought, too. But playing games in the basement led to his developing them there, which eventually led to the founding of Epic MegaGames (now known as Epic Games) and the ground-breaking first-person shooter Unreal, which took the PC gaming industry to the next level in 1998.
"Unreal was the first 3D game with panoramic outdoor scenes, and it set a new standard in terms of vivid artwork and lighting," says Sweeney. "It really changed gamers' expectations of 3D gaming from then on."
Working with James Schmalz, Cliff Bleszinski, and others, Sweeney built the editing tools that eventually turned into the full Unreal Engine. Unreal was in development for nearly four years and was a huge risk for the tiny company. But it was a hit, and more important for the industry, Unreal introduced a revolutionary gaming engine (now in its third iteration) that has served as the platform for dozens of other titles to this day.
I'm sorry, my answers are limited. You must ask the right question.
