The Witcher Developer Speaks Out On The Loot Box Controversy

This sometimes applies for games like GWENT or Hearthstone, where some cards can be traded or stored and sometimes what you get is what you're stuck with. Then again, some card packs are also available in themes, so even if the items themselves are random you have an idea of what cards you want/need from a certain category. But as mentioned, the game is also free-to-play, so there's no premium barrier to entry.
