You seem to be making a lot of moral judgments in your language: for some reason, your son’s preferred activity (gaming), which has been repeatedly proven by social scientists NOT to be harmful, and is a safe, COVID-friendly way for him to interact with cohorts, has been restricted (by you), and you then expect him to cheerfully sit around and think of interesting discussion topics (other than gaming, which bores you), bare his soul, and indulge your need to feel like the good guy by tossing a frisbee around in the yard with you. Kind of self-centered. You’re not that exciting, Dad (or Mom)!
For Gods sake, he’s been stuck at home with two parents who seem devoid of empathy and perhaps suffering with memory loss from their own childhood.
Do you remember how tedious it was attempting to explain the dynamics of situations to your parents? You (as a child) didn’t have the cognitive processing capabilities to process it quickly, let alone explain it to someone who had power over you!
Being alone with adults isn’t a whole lot of fun either.
Game theory is an effective way to change behavior. It clearly works in other areas of your sons life. Increase your sons game time out of the gate to increase goodwill/trust, and give him ways to earn more — e.g. a bike ride scores an extra two hours, etc. Be generous. Remember that a lose-win situation always devolve to a lose-lose situation. Stop calling him lazy — that’s not accurate and you can do better.
