You can play as a female protagonist, through the entire game.
More female friendly and inclusive overall.
Superior import system.
Superior romance system..
And what does everyone else think DAI does better?
I am torn on this, but I hate viewing romance as a system or game feature, though that's how it usually feels in Bioware games. I have said time and time again how I desperately crave for a romance subplot in a future Bioware game to be more in service of the story and have overall more attention to detail than the one that ends abruptly after the initial romance is completed and at this point I think writing for 8+ romance arcs at once is overkill and it makes it harder and harder to make those romances involved in the actual plot.
In The Witcher 3 I loved how they, because the entire story is based around a personal story for the protagonist, used the two possible romances in clever ways to make hard choices for the player. In one of them you literally feel like your potential love interest's life is in danger and that, if you go further with the actual mission at hand, she might be killed.
Plot-wise there was nothing interesting at all in DA:I's romance subplots, which is why I'm starting to feel like Bioware should reduce the total romance amount to 4 at max so there is some for every player, still. Narratively I felt Cassandra and Solas both had the most relevance to the main plot, but it was all just talking and no side-quests or main quests with them that involved romance very well (but I did love the incorporation of it during the ball in Orlais. Dancing with your LI was good)
I don't care how controversial this may be to be saying, but at this point their inclusiveness is directly holding back their ability to do storytelling well.
