I'm in my mid 50s and don't agree. Maybe they were for you, but I have many fond memories of games and gaming. There is a balance, of course, and maybe you spent way more time than I did, but even now I think they can be a great thing to do. All the fantasy/sci-fi reading I did? I kind of regret that time though. Definitely regret most of the time I spent just channel surfacing back in the "corded" TV days.
I honestly wish I had more time to play different games.
