Gaming is the most common hobby there is for males. And that includes men who do a lot of sport. They regularly happen to be gaming a lot. School drop outs game a lot.

Non nerds and non dorks have hobbies, always had. Having hobbies is quite normal and used to be normal. And frankly, playing computer games was popular among popular young boys for whole generations now.

"Dorky", "nerdy" never really described average gamer. It described small groups of people who had social issues regardless what they did - including sport.
