13.: Diablo 2
For many, Diablo 2 defined the action RPG genre with its combat mechanics, diverse skill tree system, and host of playable character classes.
We’ll go out on a limb and say that Diablo 2 is by far the best game in the action RPG genre, defining the teenage years of many a video game enthusiast. It remains—to date—at the top of the pile where rests the likes of its sequel, Diablo 3, would-be contenders to the throne like Titan Quest, Path of Exile and Torchlight 2, and a host of less stellar titles. They’re right there with countless broken mice, ruined by the constant click-click-click combat mechanics of the game.
