there’s a balance. 2.5 hours spent on average means there’s kids spending much longer on this each day. i get there’s a creativity aspect to it but it still seems like a lot of time, to the point where it’s likely bordering on addiction level.
I feel you haven’t played MMOs or online games in general. Yes, they can become a time sink, but there are worse time sinks out there ;)
Edit: Note that I and others from my generation grew up spending hours playing MMOs, and we turned out fine. As responsibilities come up to the forefront, the majority of people adapt.
I think the more concerning trend is social media addiction. With games, there is at least an interactive element. Social media use is as passive as you can get.
