id does the cutting edge of video game graphics.
They invented the first person shooter. They were the first people with HDR lighting. The way things are looking, they'll be the first with ray tracing.
Very innovative and always pushing the boundaries. Crytek just refines the boundaries to a level of unmatched purity.
But yes, aside from Return to Castle Wolfenstein on the original Xbox (which I played the holy hell out of), for some reason the id engine never translated well to two analog sticks and some triggers.
