If you've played Dragon Age: Inquisition, you'll probably immediately notice that this doesn't look like Crestwood at all. In this video we see a vivid, thriving area filled with soldiers and castles; the Crestwood we got in Inquisition was gloomy, rainy, and infested with demons—at least until we completed a certain sidequest. But even after that, it didn't look much like the Crestwood in the video..

Aesthetics aren't the only major change here. In the PAX demo, the player got to make some big choices involving his army's movements, choosing whether to send the Inquisition to save Crestwood, have them stay with injured soldiers, or return everyone to a nearby keep. (Keeps were emphasized heavily in this incarnation of Dragon Age: Inquisition, as we'll see in a bit.)

The PAX demo also showed a timer bar called "Inquisition Keep Strength"—a visual representation of enemy forces attacking one of your keeps, which presumably would have a big influence on how quickly you had to complete missions and what decisions you could make. None of this is in the final game.

There's more. "Sometimes we wanna test whether or not you come prepared," says Dragon Age executive producer Mark Darrah in the demo presentation. He then shows off a section where the player must set some boats on fire to prevent enemy armies from escaping.

Of course, none of this happens in the actual game. Antivian Fire is real, but it's a combat grenade—you never use it to burn down boats. There's very little environmental interaction to the extent that was shown here.

Wouldn't this have been cool?

Part two of the demo, which starts with a boss battle and then takes you through more activities in Crestwood, also shows a whole bunch of stuff that just never appeared in the real game:

There are a lot of locations here that were either scrapped or used for different sections of the game, including a cut-scene that transitions into the aftermath of that decision the player made earlier in the demo. (He chose not to save Crestwood.)

One quick shot of the demo's save files reveal a couple of locations that also never actually made it into the main game—Nahashin Marshes and The Southern Desolation. (Frostback Pass isn't a thing either, but the area of Haven is set in the Frostback Mountains, so those could be one and the same.)

Maybe that'll be DLC one day?

Part three of the demo video is set in the Western Approach:

This entire segment—perhaps one of the coolest parts of the demo and a major selling point for Dragon Age: Inquisition—is maybe the most jarring to watch today. In this section, Mark Darrah walks us through the invasion and capture of a keep in the Western Approach—which is a lot different than the keep capturing we saw in the final game.

As the demo player approaches the keep, Darrah notes that you can weaken enemy defenses by doing things like drawing out their troops or poisoning their wells. None of this actually shipped with the final version of the game, although in the Dragon Age we played, once you claim the keep you can get a quest called This Water Tastes Funny, in which your keep's well has been poisoned and you have to go find fresh water. Now we know who to blame for that.

During PAX, BioWare put an emphasis on environmental destruction: There's a section during combat where the player can spot archers on a rickety bridge, then take them out by smashing a ladder and knocking them all down.

But, no, we didn't get any of that in the final game. [UPDATE (5:44pm): Some readers point out that you actually can still smash the rickety bridge in that keep, which is a fun little easter egg. It's clear that environmental interaction in the final game isn't even close to what they originally imagined, though.]

Of course, games change in development all the time. It's fascinating to look at what Dragon Age: Inquisition once was, what the game BioWare debuted to the public could've been. We may never get to play some of this stuff... or we may eventually see it turn up in DLC. Either way, it's a small glimpse into the development of the game, and a reminder that what you see in a preview is often not what you get in the finished product.
