Since I've played the Diablo 3 beta to death, I've been sniffing around for another ARPG (action rpg) to play. Someone posted the name of the game Path of Exile in the D3 forums so I went and checked it out.
While it's still in beta, it will be free to play (not pay to win), and its every bit as fun (if not more than Diablo 3). The storyline is still under wraps, but the gameplay is incredible. All the aspects they removed from D3 over D2, PoE has in spades (ie massive skill trees, etc.). Only the first 2 acts are available to play, and 5 of the 6 classes (the 6th is still unrevealed other than it uses Int and Dex as primary stats).
