Wait, this may be semantics, but can it be considered gambling if you can't walk away with nothing? Don't get me wrong, as a self-identified whale in games with predatory mechanics like Fate Grand Order and Fire Emblem Heroes, I'm not trying to defend the system, but it's not gambling (unless there's a legal definition for gambling I'm unaware of that completely contradicts me). Ideally, I think I'd like it if under age kids couldn't even see, let alone get access to microtransaction sections in games. Everyone over 18 (like my weak willed self) should just 'gamble' responsibly. I don't know how you enforce that though.
