Roblox should be outright banned in the EU or at least the top 100 games all qualify for what would be considered lootboxes/gambling and generally predatory behavior. Basically every single action you can do has a "robux" alternative which is faster/better + boosts cost robux. Then there's the worst of them all: trading card games.
Another problem is that nothing carries over between games so as the algorithm shifts you're forced to spend robux all over again.
