Fully agreed when it starts interfering with your life you should reassess as with anything. But honestly I see gaming as a further place to connect with kids if you enjoy them. Something like Animal Crossing, Mario Kart/Party or Jackbox Party Pack can be some of the best bonding experiences out there. And it also lets you teach your kids how to have a healthy relationship with games/dopamine.

It depends on degrees. If you're going to lose your job and your wife is about to leave you stop doing it. If you just did 12 hours of work/chores/put the kids to bed and want to relax with a bit of gaming? Some people would still feel guilty but I haven't a clue why.
