Adult will still have time to watch netflix, youtube or tiktok, read books, engagement bait on twitter etc.
What these games are competing against is not "free time" but any block of 15min that would go to another activity.
Given the number of people binge watching Netflix, it's a decent marketing segment.
But players who want to do that are already invested in other games. They're not going to split out time to play this new one unless it's amazing. This thing was $40 and not well regarded. No one is really surprised at this result.
I was just pointing that the amount of time isn't the real issue, it's the competition for that time. Of course, the tighter that time is the tougher the competition will be, and the better a singular live service game needs to be.
Also, back when I played Valorant, a regular match could be anywhere from 20 to 40 minutes long. Add up queue times, waiting for people to group up (because there's usually one more person who's almost online, etc), and waiting for the potato-pc users to load in, it could easily turn into 3 hours for 2 to 3 matches.
These days, I'd rather watch a movie, and be in a different chair than the one I'd spent my working day in.
Singleplayer games or Netflix you can just pause.
All can greatly filter your audience vs doom scrolling.
That's where other live services will try hard enough to be at least on the Switch, or even better, work on mobile.
