I myself bought the game for a low price a few months (6 USD, I think) back to see what the fuss was about. I found it alright generally. I did prefer the first one, but DA2 wasn't as bad as people are whining and moaning about, I found it not quite as bad as what people are saying.
The amount of hate for this game is rather amazing, however. Don't really see why people are so upset, but hey, people are weird.
orcishgamer: You can solo Nightmare mode with a mage... that should clinch it right there.
Personally I don't mind having one overpowered class in single player games. Its fun to mow down things easily, for me anyway, I can see why people would be turned off by that though.
