John Carmack's contribution to the field of video games was revolutionary. He was the pioneer who brought smooth side-scrolling to PC gaming (e.g. Commander Keen) as well as 3D graphics to video games (e.g. Wolfenstein 3D, Doom). Seeing as how FPS games are one of the biggest (if not the biggest) genre of video gaming out there, Carmack has had an immeasurably massive impact on the industry. It's fine if people want to just play games, but don't belittle the titan whose shoulder countless subsequent developers have stood atop.
