I understand that, I just don't think it's a problem. I've spent my life being obsessed with things. Sometimes the obsession lasts a few years, sometimes it lasts a few days, and the sum of being focused on one thing to the exclusion of all else is being a very well-rounded person. Presumably the nephew is still a child, and presumably he will move on to other things as he gets older. I'll eat my words if he ends up a 60 year old who regrets spending his life playing Minecraft. Then again, if he is a 60 year old who was productive and happy and spent his free time playing Minecraft without regret, that would also be fine, no?
