I've always thought roblox was dumb, but its kind of just a playground. Kids need a playground where their imaginations are free to grow and thy're in control. Somewhere they can interact and learn how to socialize safely with other children. When i was a kid, that was a walk to the park with friends to kick a ball around, riding a bicycle somewhere, exploring, and working out some dumb activities to do... Honest question: how comfortable are you with the idea of just letting your kids go to the park by themselves for hours on end?
For better or worse, it seems like sandbox creativity games like roblox are filling that void for some kids. Not saying roblox is an answer to a problem, just that kids seem to be utilizing it as a playground where they get to be creative and in control. Not sure why I'm bringing this up. It's just a thought that occurred to me recently.
