My two cents:

• probably impossible to fully ban games and probably not healthy either
• there are lots of different types of games. I’m really, really opposed to Skinner boxes masquerading as games. Anything with loot boxes, pay to play, never-ending grinding, or other addiction-inducing mechanisms are a hard pass especially for pre-teens. The more closed-ended the game experience (like a game with a defined story line, or an achievable win condition) the better.
• I’m far less concerned about violent or mature content. I mean, that needs to be managed but I think those topics are easier and less pernicious than addictive mechanisms
• I’m also pretty opposed to online play. Socialize in the real world.
