Although game technology is a term 3D shooters would like to reserve, every game has an engine. Although great gameplay is by far the most important point to make a great game, graphics and sound are the most important suppliment. Game technology is even more: It´s not only what you see and hear, it also plays a major role for the gameplay itself. A good example is a physics engine - it´s invisible, but it can make the gameplay better through a more interactive world. And yes, maybe more realistic, but that´s not really the point - if you ever shot at a barrel you know it doesn´t move even an inch (and it also doesn´t explode, even if it´s filled with green slime). Instead the bullet flies straight though it. By the way, they also fly though car doors, so never try to hide there like in a Hollywood movie.​
