According to sources that come up in Google (bureau of labor, indeed, glassdoor, salary.com) the average nation wide software engineer salary is close to that plus or minus $5K.
On HN it feels like nation wide game industry numbers are being compared to the salaries of the best engineers at the most successful Silicon Valley\SF tech companies. When you compare against top tier companies we're looking at a $20K+ jump. But if you start comparing against top tier game developers like Valve, Riot or Naughty Dog you get comparable results.
I know that salary surveys are understandably taken with a grain of salt on HN, but I feel like it's a better yardstick than the "common wisdom" that gets thrown around.
/go back to moving bits from one column to another.

On the other hand, I don't think a very large portion of game development teams are engineers anymore. Not only are the tools much better, there is much more focus on other things like art, sound, marketing, design, etc...
It's a good point that the proportion of employees who are engineers is probably lower than in the past. I wonder how engineering vs art/music salaries compare.
