I’m confused. I’ve played Genshin, and I don’t remember any sort of loot box system in the game. There’s a gacha system which seems to be what the article keeps referring to, but that’s very different from what I think the average user considers a “loot box”.
I feel like the difference is the loot “box”, itself. Granted, I’ve not played any loot box games since Team Fortress 2, but in that game the box was an actual inventory item you could store and open whenever you wanted, and those items would always be from the same pool.
With Genshin, you’re basically just pulling from a singular, infinite loot box that rotates its reward pool. So you can’t, as a player, decide to open a Year 1 item when it’s not in the current rotation.
It’s a small difference, but I feel like that’s why we have separate terminology for “gacha” and “loot box” games.
