It wouldn't surprise me that DA:I did well commercially tbh, I unironically enjoyed it quite a bit at the time. Sure I have some criticisms too, one of my main ones is in fact that I think the writing was "too good" (Whoa! Hear me out!) - If you're a lore-buff and play games mostly for the story, there's a lot of foreshadowing and clever little teases and details throughout the game, which only makes sense once you know how it ends and the "cliffhanger". So in a way, some of the lore and storytelling was too convoluted and clever for the majority to really even notice in order to appreciate.
