I know people, mostly older people who grew up on that new thing television, that watch it all the time. They even go to sleep in front of the TV. No one thinks that's abnormal or calls them TOOBERS or something; although, maybe they did in the fifties or sixites when TV was still pretty new. Gaming has only hit the mainstream in a big way this last generation. It was a fad in the eighties, then a thing kids did in the nineties, then a thing you did after school with your high school/college buddies, and now it's something you live with. It's everwhere, in everything. Pretty soon, no one will even notice that you game, it will be assumed and the term GAMER will become a thing of memory.
This reminds me of something I heard once about technology, how it starts as a novelty, then something a niche audience uses, then it becomes unbiquitous and no one notices it anymore. It's taken for granted and assumed in every situation. I think this might be happening with video gaming; although, I still feel a little bit the outsider for being into it so much.
