I became absolutely hooked on the game, and definitely got my money's worth. But have some criticisms.
In some ways, it's TOO big, I don't see much replay value at this time, don't want to start all the way from the beginning. (Though I do see that many do multiple playthroughs, so maybe that's just me.)
Don't like that you are the "Inquisitor." Too many negative connotations. You're supposed to be the good guy!
The music isn't bad by any means, but can't hold a candle to Inon Zur's music from the first two. The camp theme from DAO, the Hawke family theme from II, just beautiful.
I ended up with 215 unused power points, what is the sense of that?
The story isn't as rich as the first two.
Would have liked to have re-visited Orzammar.
Would have liked to have visited a big city, with its sights and smells and characters. The game is mostly villages and open land.
Wanted more banter...untriggered conversations happen only very occasionally. A consequence of making the game so big, I think. There is so much dialogue they can write.
Too many codex entries, considering all the stuff to be read that aren't codex. Seems like they spent more time writing this stuff than dialogue. I hardly ever read them.
To me, most party members are fairly unlikeable. Solas, Sera, Vivienne, Cole (though I realize they have their fans, especially Sera.)
So many side quests, especially the fetch ones, the main plot gets lost in the shuffle, maybe that's because the main plot is a bit thin.
Not clear if you are better off creating your own weapons and armor, or using the ones you pick up throughout the game. I think they should have just stuck to being able to modify, via the slots, the armor and weapons you pick up.
Had to buy and Xbox 360 controller because the game isn't mouse friendly like the first two. In those, you could play virtually the whole game with just the mouse.
Couldn't get Hawke to look like my Hawke because of the beard choices (mine had a smaller goatee than what I could select).
Morrigan...I thought her appearance somewhat unsatisfying, both in her looks and personality.
The final battle is nothing special.
