You can see a correlation between healthy and unhealthy games in their icons.

Ungealthy games are mostly high quality 'renders' for lack of a better term. The healthy games have a much less attention grabbing 'lower quality' icon.

That observation suggests that if we want to improve player health, an effective place to start is to set up pro-bono or subsidized initiatives to create very high-quality, eye catching icons for the games recognized as healthy in order to help them compete. That's by no means an exhaustive solution - part of this is survivorship bias too. The devs are incentivized to invest in the dark pattern games that generate plenty of revenue for comparatively little effort and those investments include more frequent feature additions, bug fix and content updates. Services to buttress these offerings for healthy games would also be important.
