I have to say, after spending about 20 hours with it so far, that Origins is still my favorite. The controls in inquisition are simply not as good as origins, whether we're talking about the mouse and keyboard or the console controllers, though at least the PC version has controller support this time around. The leveling system is basically the one from 2, which again means far less customization than in origins. Combat also leans far more towards the second game, so again less tactical. Control over party member AI is stripped way down from previous games, which means you'll want to be handing out individual instructions more often on harder difficulties, but that's rendered frustrating by the poor 'tactical control mode', with its wonky controls, frustrating view, inability to queue multiple actions per party member, requirement to hold the trigger (while pointing the view at the enemy you want to target) to advance time, etc. You cannot simply select your target and rely on your character to attack them until you tell them otherwise, and targeting in general is fidgety and awkward. As is the healing/barrier/revival/potions system. As is the surprisingly low level cap (mid 20s soft cappd in single player, 20 hard cap in multiplayer - not that you should bother with that mess), which can leave you with half built characters on your first few plays..
As for the multiplayer - that's a tacked on multi-micro-payment cash grab nightmare avoid it at all costs.
The game's also somewhat buggy. I've had occasional issues with sound, dialog, animation, non-responsive allies, and the like. Hopefully those will get ironed out sooner rather than later, but unfortunately Bioware's (or more likely EA's) engine choice means fixes from the modding community are unlikely, and we can expect little to none of the value added by the community that made Skyrim (or the original dragon age, for that matter) so much more than anyone developer could have produced on their own. For instance, while I absolutely love the original dragon age, I can hardly imagine playing the original without a fixed version of the shapeshifting tree, or Ser Gilmore, or the like.
As for the appearance of the game - it's mostly pretty enough, but the hair is a nightmare. turn the static meshes to high, or all characters in the game will sport ridiculous high gloss plastic lego helmet hair. And even then, the facial hair always looks like a zero effort cut out badly photoshopped over your character's face.
On the up side, the supporting cast and dialog is great, as one would expect from Bioware, and the game world and scope are huge, in stark contrast to DAII. Unfortunately, I've been hearing some buzz that the ending of the game feels somewhat rushed and anticlimactic - yet another bioware game with a climax and resolution that fails to live up to rest of the game. That's becoming something of an unfortunate pattern.
None of which is to say I don't like the game. It's very good, but most of its positive qualities are described better elsewhere. I still very much enjoy the game, especially it's sheer size and scope. It is simply huge. But my favorite dragon age at the moment remains the original, largely for gameplay reasons, but in no small part because of the modding community that the original supported and allowed to enhance the value of their game, rather than fighting against in the interest of making a few extra bucks on weapon pack DLC. It's quite clear that Bioware/EA was looking at the juggernaut that Skyrim was and is when developing this game. It's a shame that they missed the memo on how important the modding community was to that ongoing success.
