4. Path of Exile
Path of Exile is like a free-to-play version of Diablo 3—an action RPG. Players choose from several different classes, each of which comes with a wide array of skills, which happens to be so vast that looking at it might even give you a headache because there's just too much to choose from. With that much freedom in the offering, it comes as little surprise that players are able to come up with diverse character builds with which to play the game.
