But I would caution against being too picky about single-player experiences. The most meaningful games for me were not generally story-based, they were "play-based". Exploring mechanics, exploring a world, seeing what might be possible, what might lie out there to be found. Zelda, Pokémon, etc. A game doesn't have to be a work of literature to be meaningful and worthwhile; children in particular benefit from play. I would cite Minecraft as a good modern example of this ethos (which can of course be played either alone or with others, and is valuable in both modes).
I categorize this as "maybe". If you're a physically fit child with good hand/eye coordination, playing ball is fun. If you're not, due to genetics, weight, or illness, it's closer to torment.
Also, playing ball is almost always going to be competitive - there are no bots and only rarely cooperative objectives involved.
Depending on the kind of "ball", but your kid goes to school., no?
that's way more dangerous than playing outside in the sunshine. from a covid perspective.
Of course, playing with a ball in a field might be better, but, covid.
I don't allow them to play single-player games so much, unless it's something original, story or experience-based. Undertale, Braid, Journey, etc.
Certainly nothing 'infinite scrolling', with in-app purchase level-ups, etc, which are obviously just calculated to be addictive.
