There are many things to like in DA:I, many of which have already been mentioned in this thread. Here are a few of mine, in no particular order:
The Hinterlands -- yes, I realize some say it's mundane. Contrary to that opinion, I didn't want to "Get the heck out of the Hinterlands!!1!!". Matter of fact, it's one of my favorite zones. It's generic done right. I enjoyed the landscape/terrain, the smaller quests, the larger quests and more. In my opinion, it was/is a fantastic starter zone.
"Collect 10 Ram Meat" and other generic starter quests -- pays homage to starter quests everywhere. They're comfort quests (like comfort food).
Dorian -- hands down, my favorite of all the characters. Well written, well developed, well drawn and well voiced. There's not a single thing I'd change about Dorian. Hmmm ok, maybe one thing -- we could cut those little curlies off his moustache...
Cassandra -- easily my second favorite character. She's secure enough in herself to be able to question and challenge her beliefs and outlooks. That's a confidence most people don't have.
(semi) Open World -- so many diverse places to explore! To paraphrase my friend Lydia, "Hey, there's a cave! Wonder what's in there?".
The change in Crestwood -- unexpected and welcome.
The Fade -- loved this iteration of The Fade.
Astrariams -- I loved these! I'm a big fan of mini-games and puzzles in games, but not when they gate story progression. Thankfully, these puzzles were totally optional. I did them because I *wanted* to.
Flower and rock collecting -- again, apparently many people found this to be tedius busy-work or filler, but I thoroughly enjoyed it. For me, gathering/harvesting is a favorite pastime in many games, online and single-player. It's relaxing and rewarding, especially when I find rare specimens. Oddly enough, I can't stand the idea of flower picking in the real world (boooooring!), but for some reason, in games, it's the bee's knees.
Requisitions -- an easy way to build both Power and Influence. And gives yet another reason to stop and collect the flowers.
Dark caves, no torch -- at first, I thought I'd hate this feature. After the first cave or two, however, I grew to appreciate it. It feels very organic.
No healing magic -- again, at first, I thought "What the heck were the devs thinking???" Over time, however, I realized it made me battle more strategically (I do wish I could mix potions out in the field, however). Having completed the game on Normal, I'm now on a Nightmare run and, for the most part, I still don't miss healing magic. It would be nice to have, sure, but the lack of it is not as much of an issue as I initially thought it might be.
Encountering characters from prior games -- Nice! Can't say much more without spoilers...
I'm sure there are more but that's enough for this post
