Diablo III: Reaper of Souls

Nobody really knows, but D3 is a great game now. It wasn't when it launched but with the new patches/expansion they've already released, the game is vastly superior to what it was when it came out. It has much more of an end-game vs what D2 had (endless baal runs). I'd definitely give it a shot if you're wondering about it. Nobody knows if they're planning another D3 expansion though.
