Some non-spoilery thoughts on the game as a whole.
I loved DA:I. Not as much as Origins, but as much as I could have hoped. I play Bioware RPGs for the story and characters primarily, and on that front it thoroughly rewards players who have been paying attention throughout the series. However, it has one major flaw: filler. The Ubisoft flaw. Once I arrived in the Hinterlands near the start, I spent a full 20 hours on filler before advancing the main quest. 20 hours in a Bioware game without any proper conversations or story stuff. That in itself is insane, but the fact that there were many more areas (none quite as big, but all of them substantial, in the realm of 5-15 hours each) is astonishing, in both good and bad ways. Exploring the scenery was a pleasure, putting aside a few issues with navigating cliffs and the such. But I don't play Bioware games to collect 10 of something or kill 5 of someone. It's 20 hours of exemplary Bioware storytelling dropped across a 90 hour Ubisoft game.
And yet I enjoyed the exploring bits. I don't know whether to applaud Bioware or demand a tighter cut from them. When I play it again, and I will, I don't know if I'll bother with half of the game. I think you could comfortably skip huge portions of it to little detriment and complete it in 40 hours. When I think back to the Mass Effect series, that had some filler (anyone remember trying to find all the citadel keepers in MA1?) but most of the sidequests were excellent and involving. Aside from the character-specific quests, DA:I didn't have any sidequests as far as I can tell. Yes, you can optionally hunt dragons and solve a few ancient ruin puzzles, but they don't advance the characters or story in any meaningful way. That is my quibble with the game, and it's why Origins still takes the top spot of the series.
Back to the true core of the game, the characters, I think the cast is mostly great. A replay will demand more attention on some of them, but the only one I think was out of place and basically a bit shit was Sera. I simply didn't click with her at all. Cole was a bit annoying, but his endless waffling appears to have some esoteric clues which demand closer inspection. Iron Bull is a fucking triumph, as are Varric and Dorian. As the comedy trio, they headed up my A-Team for most of the game. I warmed to Josephine eventually, and Leliana was a stronger character than in Origins (if a little underused at times). Cullen... I have to give special praise to Bioware here because they took a risk and it paid off. Cullen verges so perilously close to being a whiny emo at times and yet he never becomes an embarrassment or a nuisance. He has a true development of character built over all three games, with very compelling reasons for being distrustful and moody. He could have been a disaster but I think he turned out to be one of the best characters in the game.
I'm at a loose end now. I've spent so much time with this that I don't know what to play next - everything will seem tiny in comparison. I might play a bit of Elite until I can stomach another go at Inquisition.
