I actually might play it. I liked Diablo 3, but don’t have time for games like that. But if I could have it in my pocket and just play when I have some time to kill, might be fun...
It uses popular mechanics that work, which are found in lots of other games of this type.
It's like saying Gran Turismo is same as Forza Horizon because you control a car.
I won't be getting it or anything, I just think that the reaction has been over the top, especially if you sit down and read what Bliz have said about it.
