It greatly depends if I have to admit, video games themselves aren't necessarily bad like if I have children I wouldn't make them to stop playing video games but I would definitely limit their time being on video games when they are young, like maybe between 30 minutes-2 hours it would depend but regardless of that video games are an "escape" in many cases like many kids sadly don't have friends to go out with and instead they spend their time online because that's where they could feel "welcomed".
Also one another thing is that ton of parents don't have the budget to buy their kids like crafting tools, drawing tools maybe a bicycle maybe a toy or whatever and like video games are basically just thrown to the child because it's "cheaper"
But honestly the main problem in my opinion is the environment like because of how unsafe the outside can be for a child, many parents don't allow their child outside or they really limit the child's time and where they can be and go and like when that happens the child will just go play video games because they are more "free" there, also many areas don't allow children to play like for example football and ect
Also Covid played a really big role in it by basically not allowing us to go outside, there was nothing to do other than playing video games
So overall the main reason kids are addicted to video games in my opinion is because simply of the environment and it makes me sad not to see children outside enjoying themselves like I have younger cousins and it makes me really sad seeing them closed almost all day in their tablets playing video games (and it's not even the good kind, it's fucking those Italian brainrot games on Roblox) and like they don't even go outside with friends, like today world is sadly really wicked for children
