To me it seemed to try to say that most research done so far on video games is mostly about how violence in games affects people, not the positive benefits. Which is probably true that the majority (for a while at least) was about that.

Tchia has a tiny bit of fighting, but felt like a cozy game the whole time I played it. It was slower paced and easy to just explore.

Outer wilds has a lot of mystery to solve but is very relaxing and pleasant.

Both games I felt perfectly happy to just enjoy the sights occasionally.
