If you chose to bike to work every day, I would call you a biker. If you watched a movie every single day, I would say watching movies is a hobby of yours. If you went to a rock climbing gym every day, I would call you a climber.
Driving, and some other fields like cooking, are quite different. You're not choosing to engage in that behavior - it's a requirement for your life. Same with cooking food. You need to get to work, you need to eat. You don't need to play Candy Crush on the train - and obviously, many people don't.
> And my general opinion: don't worry about identifying yourself as a gamer because of some stigma.
I don't mean to be a negative ned, but I'm not talking about the "neckbeard loser" stigma. If you're not sure what I'm talking about, that's probably for the best.
