Depends what counts as an in game currency, does a game where you earn currency in-game and spend it in-game count as an in-game currency? What about if players can trade it?

Nah thats usually how those start out afaik. They start with a guideline and a grace period. Then when the grace period is over there is a warning period and after that it goes straight to fines.

The CPC Network will monitor progress and may take further actions if harmful practices continue.

Lets see what happens.

It is in part. They are hosting workshops and publishing these guidelines so companies can work on it on their own merit but they will also take further action if the harmful practices continue

It seems they are saying that these are already enforced:

The key principles and the Common Position are based on the existing general rules of EU consumer law directives that apply to digital services and digital content provided to consumers, including video games. The Commission will continue to examine these topics in the context of forthcoming consultations on the Digital Fairness Act.

It's stuff like chat control that make me hate the EU sometimes.

because the people who hate the eu are the people who are wrong.

This is especially funny in South Korea. Go to a Casino and burn $2000 and you may even get jail time, but gatcha is A ok.

It'd be fine if it was limited to like 1-5 dollars per account monthly with a yearly maximum. Not a 100 dollars at a time.

Or, just stop games from selling in-game content?

Every skin is a texture or model swap, every "exclusive" always exists in the files, every in-game currency is fabricated.

Games try really really hard to make you pay for something that is copy and pasted

If the conversion rate isnt 1:1 or its not directly using € in the game then i would call that confusing or deceptive.

The first two principles for virtual currencies that they have listed are "Price indication should be clear and transparent" and "Practices obscuring the cost of in-game digital content and services should be avoided", so if EVE is honest and up front about it then it should be fine

These seem to be the four major points:

clear and transparent pricing and pre-contractual information;
avoiding practices hiding the costs of in-game digital content and services, as well as practices forcing consumers to purchase virtual currency;
respect of consumers' right of withdrawal;
respecting consumer vulnerabilities, in particular when it comes to children;

First one actually seems pretty well covered by Warframe already. Second point can be met just by displaying the real currency price next to the plat price, calculated based on what people on average give per plat when purchasing through the Warframe website. Third point... Yeah that's going to be a point of contention for sure. That'll require a redesign of the plat system. Fourth point I'd also say Warframe does. Their 'oh shit' moment when they ended up creating a slot machine with, what was it, kubrow skins? Demonstrates them actually caring about this already. Basically they saw people interacting with a new mechanic much like one would a slot machine, and then soon after rolled it back and refunded everyone who had spent money on it.

Considering you can't sell platinum for money, you could add complexity by converting it to another currency when exchanging hands. No value lost, exact same ratio. You buy platinum, you spend it on the store or it decays when you give it to another player. Platinum carries real world value, decayed doesn't. Would that work? The only reason for doing that would be to obfuscate the fact platinum has real world value. The players being constantly aware of the fact might mess with the economy.

Honestly, their monetization is really something I could never criticize.
