Yes you are.
There is no way we can say what is healthy or not healthy - it depends on your kid and circumstances. The only time I get worried about kids who play video games in extreme, or who only play video games (playing more than 70% of non-school, non-work time playing video games).
I remember I played a computer game every day for almost a full year. I was in 8th grade, and I remember coming home, doing my homework, and playing until 9 or 10 at night. It was fantastic. A great escape for me during the throes of early adolescence. Over the years, as a teacher I saw the educational value of games in my classroom. I still enjoy playing computer games casually.
The issue becomes when important stuff doesn’t get done. Then you need to sit down, spend times with your kid and talk to them. If there is someone who can give them a dutch uncle talk all the better.
