My feelings toward this game can be summed up in a simple sentence - I'm not mad, just disappointed.

I played through the entire DA trilogy; Origins was hell of an amazing start, 2 became one of my favorite games. I was insanely hyped to play Inquisition as the series found its way into my list of favorite media.
Although in the beginning the game seems pretty fun, it quickly turns into a neverending grindfest. You want to progress through the main plot? No problem! Just do several unnecessary side quests to gain some Power to unlock the main quests. You have to collect so much, I'm surprised there weren't lootboxes.
The companions in this game feel more detached than the others - they work with you because you're THE Inquisitor, and Maker doom us all, because if we don't cooperate, we're gonna die. There's no true connection like in the previous installments. Which brings me to another point - the protagonist.
The protagonist is a blank page in the worst way possible; throughout the game they barely show any personality, it's like they're a placeholder, a weird stop between "make your own character" and "this character has a specific story". They get into the role of Inquisitor unnaturally, barely showing any stress aside from maybe a couple conversations.
Romance in DA was one of my favorite parts of the games, even if the mechanics were flawed - DA:O progressed too fast with the approval system, DA2 did it just right with quest-like interactions. Meanwhile DA:I progresses too slow due to the "gain power to unlock plot" system. I nearly forget about the romance due to how slow it works.
It might be just me, since I play for the plot, but as someone said, this game feels more like an MMO. Kill enemies, do 700 boring sidequests, and maybe you'll get a good main quest as a treat. Maybe.
Dragon Age has strayed from the traditional RPG genre, with DA2 being more of an Action RPG than the first game. But DA:I brings that to another level, barely feeling like an RPG. To return to my beginning statement - I'm not mad at this game for what it is. I'm just disappointed.

To sum this up, if you want to play this game, go ahead. But I recommend claiming it for free or buying it on a discount, like I did. It's not worth the full price.

Game runs extremely well on steam deck, but requires significant tinkering to get there. Performance is good and controls are great for steam deck once you actually get them working.

Problems:
- game has good Gamepad support, but doesn't recognize Steam deck as controller. If you manually enable Gamepad support, it becomes unresponsive and you have to force quit it
- EA launcher makes launching the game clumsy, and because it keeps changing, you may need to occasionally change proton versions to keep being able to start the game

How to get properly working on steam deck:

1) install
2) force proton-experimental to get past the EA launcher for the first time. You may or may not need to do this one time in desktop mode
3) install this custom version of proton-ge to get controller support working: https://github.com/cammoore1/DAI-proton-ge-custom. You need to use the tarball method detailed in README. Use the latest tarball in releases, at the time of writing 1.0.4 worked for me.
4) close Steam from system tray in desktop mode and use ProtonUp-Qt to enable the custom version of proton-ge for this game. For me this was necessary, because steam did not detect it in the "Force compatibility" settings drop down menu even when I restarted steam.
5) change the steam input settings to "Gamepad with mouse trackpads". Edit the layout and set right trackpad click to left mouse click. This is needed because controller support is disabled in the games settings by default.
6) start the game, go to settings -> controls -> set controls from Mouse and keyboard to Gamepad.

Time to catch up and prepare for Dragon Age: Dreadwolf!

Game is full of bugs. Had to constantly either quit to the main menu and continue to progress through to where the character could gather resources (or open a door). Or the game would freeze and give you a message that the connection to Dragon Keep had been lost and you had to select Continue to connect back to the game. In some cases you had to go to Windows Task Manager to End the game entirely to close out of it. I know glitches and bugs are a known quantity with a BioWare game but I don't recall Star Wars the Old Republic having this much jank.

Sara is perfect

Played as a female elf, which made everything pretty damn good and pretty inherently straight... But sorry, I refuse to support your "inherently queer" fantasies. I was looking forward to Dreadwolf, but no more. I'm sick of it. I hope you reap what you've sown for tainting the franchise with your bs Corinne Busch.

was not available to claim for free on epic for turkey, is not worth paying money for

Plays more like a Ubisoft title than a Bioware one. Whether you prefer that or not is up to you.

I sank a lot of time into this game, desperately wishing to love it as much as the two prior DA games. The combat is clunky and dumbed down, and the generic MMO questing feels bloated and tedious in an online game - let alone a single player one.
The most disappointing bit for a Bioware title, however, is that the dialogue and story pale in comparison to the prior two entries.

It's Dragon Age, in all it's beautiful, and sometimes frustrating, splendor. If you love Bioware, and haven't played it, you should.
