Multiple bugs in my first play through. Some minor, like NPCs/resources spawning in walls or underground. Some rather big and annoying, like having to reset option and key mapping every time you load up the game. Also had this weird hiccup where I did not get the "continue" option on the main menu. I had to go to load game every time. Experienced a oddball problem where the game would lock up every 30 minutes or so, but only when online and logged into the Dragon Age servers. Seriously, I tested it by running the game for 4 days offline, not one freeze, logged back into servers and crashed before the rerun of Archer I was watching finished.
After I broke it down a bit. Deleted all save files, reinstalled DLC and patches, a lot of it got cleared up. Still got the minor bugs, like spawning and animation, but most of the big ones fixed themselves.
Now, if they would patch in a few changes to game design, not bugs but screwed up features. Things like tactical camera basically not working around environment/being blocked by small hills or trees, no storage capabilities (seriously, every DA game has a storage chest, why not in the biggest DA game to date?), anything/everything to make horse-riding less headache inducing, to name a few...
