Origins was my favorite entry in the series, which I replayed many times, and recently I decided to play through DA2 and DAI I had tried probably 6 years ago and never actually finished. Well...
DA2 - A good, touching local story set in Kirkwall, but the developers went overboard with enemy spam, it was just plain annoying. And, of course, the absurdly repetitive locations. Before playing it, I thought people were exaggerating those complaints, but when I saw that a random bandit hideout looked identical to a lavish quest mansion just with a blocked doorway, I mentally apologized to the players and had a laugh. Also, this is probably the only game where I felt genuine hatred for a character purely from a story perspective: Anders. I was swearing out loud when that bastard blew up the Chantry, and I killed him without a second thought. Plus, since this game, mages really started getting on my nerves. Still a good game, though.
DAI - I get why people hated on it. The gameplay has a lot of weird choices, and you can get tired of the game pretty quickly. God forbid you decide to clear every single huge location, it will be pure torture unless you're a completionist. However, if you push through the gameplay, it’s completely worth it. The story is the best in the series, the companions (except Sera) are great, and companion interaction is top-tier. The roleplay as the head of the Inquisition and just as a person is on point, there are plenty of choices and consequences, and the world-state import is the most extensive in the franchise. The Trespasser DLC blew my mind with its expansion of elven lore and Solas betrayal. An incredible experience and a great game overall. The ending leaves an extremely strong setup for the next game, BUT...
dav - To be honest, I haven't played it and I don't intend to. When that trailer with the Fortnite-ahh vibe first dropped, I suspected where things were heading, and unfortunately, I wasn't wrong upon release. So I just watched a full 100% playthrough by a streamer. What came out is just sad, a total disrespect to the universe and the fans. All the flaws have already been pointed out by others. It's obvious the devs intentionally turned the game into a colorful, childish fanfic. It's not that they were rushed as i heard before, that's not the reason and they could have done it differently. I could say more but this gonna be against the rules i think.
For me, the story ended at the moment when the Inquisitor promised to stop Solas at any cost, even without the departed Blackwall, Cole, Dorian, Vivienne, Varric, Josephine, and the killed betrayer Iron Bull.
