And let me guess, you can quit any time you decide?

Try not to play for 30 days and report back with your findings. I think you are underestimating the amount of time you spend on this filler activity.

We're talking about two separate things. I was talking about being able to play a game for 30 minutes (or even 5 minutes), then set it aside for later. That could be later in the day, or several days later.

Quitting gaming altogether wouldn't have many benefits in my case. I only play on weekends, and usually less than an hour per day. It's not that I'm boasting about a lack of filler activities in my life. I have them. They're just elsewhere.

My point is that humans aren’t wired for 100% uptime, and filler activities are somewhat necessary. Any leisure activity is “filler”, and we don’t have to AB test something for it to be maximally harmful. Playing Fortnite is objectively less harmful than hurling bricks at buses, and only one of those is AB tested.
