I understand what you're saying. I hold a different view of what is well made or not. Commercial success isn't the only measure. I believe dark patterns detract from the cultural value of a thing, which is how they came to be called that. Meta is a valuable company, but they could have made less money and provided much more value to society with different practices. There's a "rising tide lifts all boats" approach to commerce, and then there's the candy crush, perpetual enshittification, monetary maximalist approach, usually with negative side effects.

But that's beside the point. I don't think League of Legends is especially predatory, I just think it's a mediocre game that was well marketed at the right time to go "viral".
