I’m not a parent so of course have no right to make a suggestion, but could parents only buy devices without an internet connection? Games that cost X and X only?
Pretty much every single game adopts loot boxes alike - as it's profitable. That leaves very options (if any) for a decent games overall - children excluded.
Children are not the only target - far from, but the argument is easier to make. Video Game industry suffers massively, lacking good content as loot boxes dominate most popular titles - the freemium model. Kids would like to play what their friends play and often online - the latter statement is not limited to kids at all.
Also a parent is extremely unlikely to limit phone usable (prime target) to no inet connection. It's doable of course but it's futile and the kids feel excluded.
