See the other reply about why the EU can't act. I'd just like to add context on the "why were they let in" front.
Hungary joined the EU in 2004. The country was more democratic back then. There were even some hopes of joining the Euro zone. Then the government of the time cocked up (basically their words), and Fidesz/Orbán, who were part of the anti-communist wave in 1989, gained a supermajority in 2010 and gradually rewrote the constitution and electoral system. Slowly eroded all the systems, took control of all the media, etc.
Not sure when they became Russia-friendly/controlled, but Hungary has been less democratic since 2010 and that's where the problems stem from. I genuinely wonder how much of it all was a Russian plot from the start and how much was opportunistic.
I agree. I was so convinced it's a hero shooter/MOBA/whatever that I checked the description and was shocked it said single player RPG. Hell, I was surprised when it revealed there is a player character.
They 100% don't seem to realise what people liked about the games.
