If it doesn’t involve real money in any form or way, it’s not actually gambling.

EU is not going to classify WoW as gambling for example, just because you can find chests in dungeons that give random loot that has no connection whatsoever with real money.

Tho they are looking into forcing every game shop to show the real money value of what you’re buying alongside all the fake currencies companies invented to hide it, but that’s a different law they’re making.
