Many people lamented that after Diablo, although many companies followed suit and released Diablo games, none of them could reach the level of Diablo.
It wasn't just about the game's difficulty, plot design, character design, and so on. The most important point was that these games didn't create a dark atmosphere.
In some games, the players were disgusted by the large number of corpses and the dark environment. However, when the players played, they did not feel any despair at all, because the characters in the game were just NPCs, not alive enough.
After dark Souls was released, the players who liked Diablo games exclaimed that it was a godly piece of work! This was because Dark Souls had created such a desperate world.
In the world of Dark Souls, fire itself was an illusory thing. Bones seemed fragile and warm, like a flame that was constantly swaying and could be extinguished at any time.
