People that buy this want the cards, keychains, and (especially) the exclusive in-game items.
Yeah, but at that rate, why not just launch a store then and sell those items? Blizzard has their own store. Plenty of franchises do. It’s so weird to see a disc version of a free game. Can you imagine if fortnite did that? I don’t remember if they ever had a disc version of their game, but if they did launch one today, people would be scratching their heads
