Diablo III is my favorite game. Everything about it is cool: Graphics, characters, story, gameplay (unlike the sequel), items and so on.
The Reaper of souls DLC complements the game perfectly. Act V 1 is one of my favorites. (Act IV and Act V).
This game (again, unlike the sequel) has the PERFECT balance of epic boss battles and fights with minor demons.
The story and cutscenes are excellent. The characters aren't far behind either. I've played through the game as each one, and EACH character has their own abilities. A sorcerer can summon assistants, a sorcerer can kill with magic, and so on. Moreover, in the game you can find partners who will help you not to bother with small demons.
In general, a great game, I recommend it to everyone.
10/10.
