Diablo Immortal won't release in the Netherlands and Belgium due to loot box law
Immortal can be played for the mainline story without spending any money at all. So far, at least up to level 40 (about 12 hours of gameplay) I haven't felt the urge to spend money. It's a little like Path of Exile in that you can enjoy the base game and the story for free; it's only if you "get into it" that you start spending money (I never "got into it). I can't help but feel it's fair to give away a really nice game to everyone, supported by the super fans who stick around to dwell in the experience without bound.
