Video games are a leisure activity. They might not be quite as mentally engaging as commenting on HN or programming, but they provide the same functionality.
Making a distinction between time spent playing video games and time spent doing other leisure activities is fairly pointless. Managed properly, there's no real physical difference between playing a video game for 20 hours a week and reading a novel, watching TV, commenting on HN, programming or any other fairly motionless activity. I know that I (as a relatively fit 21 year old) spend quite a lot of time sat in front of a computer. Physically the activity is fairly irrelevant.
Perhaps the only thing that video games have that the other activities I mentioned don't is that they have a fairly high potential to be addictive. I'd imagine most people who've played video games at any point know what it's like to play for 10 hours straight for an entire weekend. You don't have to do that, but people do.
Regardless, a sedentary lifestyle with no regular exercise will lead to health problems which increase the likelihood of death. That's something we've known for decades. Don't count "time spent playing video games", count "time spent sitting down".
