Yes, 2 had a lot of re-used locations. Some of them did make sense, as the story was almost entirely set within a single city, so certain locations are bound to pop up multiple times, especially as the game takes place over a decade or so.

But the real reason, 2 was developed and rushed out the door in like a year or something? It was a ridiculously short amount of time to develop a sequel to a game as big as DA:O. Unsurprisingly, this led to a LOT of re used assets and locations.

But though it obviously had failings, I, like some others, would probably put DA2 as the high point for the series telling really character driven stories with the most compelling cast of characters.

I've heard that, and it's reasonable however I found the level design in the first one could be a little repetitive as well so I thought some of the criticism was somewhat unwarranted.
