Diablo is one of the best action role-playing games ever created. Though not as large or as ambitious as its sequel, Diablo II: Lord of Destruction, its gameplay, music, and atmosphere truly give the player a sense of vulnerability, danger, and dread in crawling the dungeons of Tristram.
During its release in 1997, it broke sales records in the US, becoming the highest-selling computer game for the first six months of the year. It was a hit worldwide and remained one of the most popular games for the next three years. It received wide critical acclaim and won several awards.
Even after its sequels are released, Diablo still holds a unique position among isometric games where atmospheric gameplay is at its best.
