I read the issue, and they did mention that the line defining an RPG has become blurred. I think they included those games on purpose to make a point. Though it is odd they include games like Horizon and Destiny and not, say, Borderlands.

I think the definition of RPG is definitely not what it used to be. Instead of categorizing every game into a single genre, they are more like labels where a game could have one or several. Any game with some kind of stat progression could qualify for the RPG label these days.

The biggest atrocity of their list is putting Skyrim at number 1. Honestly, their list is kind of weird, but every list like this is going to have some odd elements. I liked IGN's RPG list better.
