Then do a little dissection into the game. Is it a shooter. some of the best are running on their own created engines, so if you are making models, you usually need an understanding of sculpture, painting, lighting, human anatomy. weaponry needs physics for reactions, math for mass and damage.
Gaming is a damn sight more then just computer programming. you need a lot of other interdisciplinary skills. i know one of the earlier ID employees and Kens skill was sculpting monsters. you need more then just programming. I bet you find the games they like the best are the ones that are the top titles, and they are made to look like complete worlds. so you need to understand how the real world works. get out there and explore it, because if you expect to help create a digital version of it, you better understand how it works.
