Not really since they would directly equate real money to x amount of in game currency
Thus any action you can perform with game currency would be the same as any action performed with real money.
Just because you change it from any nation’s currency to rubies does not in anyway impact the issue.
They do sell special “discount packs”… either was said game currency still has a direct correlation to real money. Direct or indirect is irrelevant and you do realize that if they tried to say “oh well its not direct purchasing blah blah blah” then they would be inadvertently admitting that they knew it was a problem and they schemed a way to try and circumvent the law which is usually in and of its self illegal. Typically carries heavier penalty than just saying…ah ok…we screwed up lets fix it sorry!
Game currency can then be spent on various items many of which are “% chance based” crafting gear for example or are advertised as % based (click the info tab on any chest it gives you a % break down of drops and does not disclose what your next drops will be).
If you’re spending money you should be able to just straight buy what you want
Also it is shown that young children - mid 20s brains are very malleable. Risk/Reward centers of the brain have been shown to activate just as much or more while gaming than doing drugs for example. This in essence wires the brain to be more likely to take part in other “risky” life behaviors (drugs, alcohol, gambling, reckless driving, or any thrill seeking activity that you can name). The younger someone is typically the less impulse control said individual has. You can’t gamble until a certain age in most places.
^^ just a guess but…that is probably the reason they’re cracking down on it and trying to at least minimize the impact its having on developing minds.
