But how much of that was actually tied to games? Maybe I'm being needlessly nitpicky but I didn't even notice the comment about lifestyle as I first read the article, tucked away near the end.

For a guy who took 3 days off work to play D3 and died at his computer? Probably a lot.

That's the point. It's an unnecessary shot at gaming, which is why the fact that the person was unhealthy is near the end.
