It's not that kids actually love the lazy derivative games on Roblox. What they love is the rush they get from feeding the gambling addiction the Roblox Child Casino was carefully designed to develop in them. Cheap games on Google Playground won't be nearly as attractive to kids unless Google also fills it with anti-features like push notifications to nag children into getting another fix when they start having fun outside of Roblox, or adding a ton of limited-time rewards to fill kids with anxiety and make them feel like shit when school, homework, or family gets in the way of earning more Robux.
What Google Playground really needs is their own currency, designed to hide the true cost of every purchase, that children can earn by making popular games. Then Google can profit from child labor the same way Roblox does. https://www.classaction.org/news/roblox-lawsuit-alleges-enti...
