This is very interesting.
My personal opinion on this is a bit split.
On the one hand, I think all (for-profit/paid of course) lootbox mechanics could be banned entirely globally and nothing of value would be lost.
On the other hand, I fail to see a substantial difference from a legal perspective between digital lootboxes and MTG card packs, which have been available in Austria for 3 decades or so.
- Both give you a random reward with different in-game impact depending on chance.
- Both are bought using real-world currency.
- Both can be traded for a real monetary value (sometimes with third party mechanisms -- with varying degrees of convenience or lack thereof).
So if one of them constitutes illegal gambling then surely the other must as well.
I guess one could argue that MTG just slipped through the cracks of legal enforcement by being more niche.
