As Blizzard's spokesperson says, you don't have to buy any of these things I'm guessing that the majority of users won't. But you'll have to suffer through a lot of boring grind instead, and you'll start to wonder how much value is your effort Diablo IV Gold.
Diablo Immortal continues from where Diablo II left off. To stop the demon Lord Diablo and his cohorts from threatening the world of Sanctuary Tyrael, the archangel destroyed the Worldstone which is an object of immense power. Now, the left-over forces in Hell are looking for shards of the Worldstone to serve their own motives. As a brave adventurer you will join forces with regular scholar Deckard Cain to retrieve the Worldstone shards and destroy them, before a new demon-lord called Skarn is able to get his hands on them.
I'm not sure about the story in Diablo Immortal. On one hand, it's got a lot of respect for the history of the franchise, picking up right where Diablo II left off and setting the stage for what happens to follow in Diablo III. The game will provide a deeper understanding of the cities and civilizations of Sanctuary and fans who have played for a long time will enjoy appearances by characters such as Xul the Necromancer as well as King Leoric from Tristram.
However the story itself is almost a beat-for-beat repetition of Diablo II. The player will assist a group woodland rogues. You'll reassemble legendary weapons to fight in the desert battle hostile shamans in a swamp and climb a mountain with barbarians -- if you've played Diablo II, you've literally played through all this before. The story beats in the new game boil down to "find the MacGuffin to destroy your MacGuffin" repeated several times. I also wonder whether Blizzard is planning to use the same strategy to expand new locations in the near future cheap Diablo 4 Gold.
