Anyone else playing or played through Dragon Age Inquisition? The storyline isn't bad, but I feel like I'm playing on rails in small boxed areas. This is definitely no Skyrim, but is better than my previous experience of Dragon Age 2.

It's not meant to be like Skyrim.  Have you played Dragon Age: Origins, Baldur's Gate, Baldur's Gate II, Neverwinter Nights, or KOTOR?  Inquisition is more like those in layout - hub-based and still non-linear, opposed to being true open world like The Elder Scrolls.  However, many of Inquisition's maps are the size of an entire open world game (a smaller one though).  The size of all of its sandbox regions combined is far larger than that of Skyrim.  I suppose you can think of it as region locked open world.
 
I just finished my first playthrough at about 153 hours.  It is without a doubt the most ambitious single player game ever made, and the plot seems to branch out even more than Origins (which has the most dynamic plot I've ever experienced).  I can't wait to replay it as a totally different character, using a different world state and different characters/choices from the first two games.

I have been waiting for the patches to come out to try playing it again. First day was not a great experience, so I decided to wait a bit. PC patch 3 is due soon if it's not out already, then I'll pick it up again. Seemed promising from the small bit I played to star.

The problem comparing the two though is the scope of the world-building.  Skyrim takes place in a single region of the larger world Tamriel and for that reason can be open-world.  DAI though spans multiple (12? I think) zones across two countries and having a completely open world would minimize the scope of the world they're building.  Having zones across the continent with vastly different geography does a better job of conveying this massive world Thedas.

Yep, so far that's the only real graphical issue I have with the game. It has some z-fighting going on. Overall it runs smooth as butter with R9 280X CrossFire.

I have played a little more. Game is still running smooth at 4K 60 FPS now when I'm able to roam wherever. I've just been running around doing side quests, I did run into a dragon when going up north more. The instant I saw the flying dragon I started running lol. 3 of my guys died quickly and I'm yelling RUUUNNNN. For my main guy I've just been digging into the fire tree and a little lightening. I don't know any good builds as I'd like to just play through on my own build, just loving the visuals and sounds at this point.
