Gaming can be very addictive but I don't think that is as bad as the alcohol or cigarettes are. I guess we were all "addicted" to gaming when we were kids, at least a bit. But when you grow up you usually don't have time to be addicted to games, unless it really got you at earlier stages of life and you can't help it.
I'd have to disagree with recent news and my experience. Blue light, which is emitted from all these gadgets are known to negatively affect eyesight and disrupt sleep, which affects focus and mood.
Personally, gaming was an escape as the only kid in the house with middle-aged parents. I had to make up my own hobbies while they can't be active with me. I'd sit for hours on "one more quest", till I realized it was early morning.
I paused gaming for a bit for college work, but still had a few non-immersive games I could play for a limited time, like Hexoscope. I am now glad at all the times I was pulled away by chores, though irked at at the "just pause it and do it later" from Mom.
Moderation is the only way yo curb it, as it is getting harder to completely ditch tech/blue light.
I feel sorry for the very young children given these devices instead of the pen and paper I got when I was bored.
Btw, I'm only 19 and worried.
