Video games are basically all clever approximations and gimmicks. Once in a while, the realism wave sweeps through, and people start touting realiatic physics, or physically-based rendering, or advanced AI systems. But it's generally not all that fun, doesn't feel right, and doesn't give designers the knobs and levers they need to fine tune things and dial them in without chaotic effects.
