I guess growing up playing the last 25 years or so kind of turns it into a habit. Of course I've had some bad streaks of overplaying which became bad for my mental health I bet but doing it in moderation feels quite good for your brain. I think there's some studies on how games like these affect you as well as it's not just hand to eye co-ordination but also a lot of strategy, tactics, timing, teamwork, etc involved.
