The first game in the series was recorded on the official channel Diablo, which is popular for studying or relaxing.
Despite the game's aesthetics, a certain old man is doing routine work, surrounded by candles and books. The scores, given the game's aesthetics, are more menacing and creepy than soothing.
Diablo IV is scheduled to be released on PC, PlayStation, and Xbox on June 6th. There will be no open beta testing until March, but for the time being, developers will keep keeping their diary entries.
