We had forced times to come off gaming and way before dinner. That meant they were available to prep food, help cook, or actually cook the whole thing. Table setting, getting drinks etc. The same with after dinner, everyone clears away and no one is sitting down until everything is washed or in the dishwasher. Dinner was eaten together as was lunch on the weekend too.
Homework had to be done to a high standard. Attitude was the great determiner. If you were shitty, no tech for you. Argue and you lose more time on it. This was established in primary school though so they knew we stood firm. If you wanted more time on tech then you ask calmly, no demanding, just a conversation. We used to have family table talks. You want something, later bedtime, something you need money for? Negotiate for it.
They also had a chore chart that they were expected to complete with no comments. That way they had a daily routine of stuff to do.
We had family tv stuff, films on weekends, board games, card games. This meant they had a mix of different activities plus the sport they did twice a week. After that they were allowed to game with their mates or each other. Dh and I both used to game before we had children. We also binged tv as children too.
I don't think it is as bad as everyone thinks. It depends on the games they are playing. If they are combat style then their blood pressure is raised, the communication and language they can be exposed to is horrific. However, my now young adult sons play games where the communication is only between you and your team and the team consists of their mates not some aggressive 30 year old trying to take down teens.
No one is stressed to death in the games they play and they have Steam accounts so games are cheaper and plentiful. They learned that if a game was causing them anger issues, stop playing the game for a bit or we would take them off it as we could hear their conversations over their headsets.
