That's personal opinion. I certainly consider Dragon Age to be very much a part of this genre, and I love the DA games, even DA2. And DA:I sold over 10 million copies.
With you on that one. DA games are definitely an evolution of the formula, and by the developers of BG to boot. Even if many don’t like the direction they took with it, it seems weird to suggest it somehow doesn’t count in discussions about the genre.
I like them too, but I do have criticisms about Inquisition in particular. More about quests and world design than mechanics though.
Oh sure. I have my own criticisms too. In DA:I, their need to fill the space of an open world with something resulted in far too many pointless trash fights. But overall, I still liked the game, still replay it, and am looking forward to DA4.
