This has already been going around from PCGamer: http://www.pcgamer.com/belgium-says-loot-boxes-are-gambling-wants-them-banned-in-europe/
And Belgium isn’t alone, Hawaii has started to look into regulation as well: https://www.youtube.com/watch?v=_akwfRuL4os
I suspect (and it is alluded to in the Hawaii video) that this is just the beginning. A bunch of other regulatory and legislative bodies are going to jump on this. I think the major question now is: how far will this go? In the Belgium case, they specifically mention not allowing purchase of anything that you don’t know exactly what it is (i.e. no purchasable random items at all). Personally, I expected this and kind of welcome it. Having dealt with some gambling issues in the past, I’ve been tempted the same way by this stuff and really don’t like all the lootboxes, especially purchasable ones.
