I'll be the first to admit that Inquisition has its issues--shard collection and other collectibles, large empty areas, an absent villain for much of the game--It's still my preferred game of the three.

I've recently been watching through some playthroughs of DA:O/Awakening and DA2 on the Codex Added Youtube channel, and I honestly can't believe I ever managed to slough through the UI issues and byzantine mechanics found in DA:O. DA2's combat was a massive overcompensation, but Inquisition hits that lovely middle ground between tactical and real-time that keeps me coming back.

I liked 2 better than Origins, as well, though, but I'm a sucker for a tragedy over the traditional hero narrative.
