The only good part of Dragon Age 2 were the interactions with the Qunari Arishok, they are basically the medieval equivalent of the Borg, they were still a hundred times more interesting than any of the cardboard cutout characters and contrived twists this game had combined.

I'm a huge fan of DA:O. Even when doing my best to have an unbiased view on DA2, it's just not good.
IMO the characters are so bleh, the story is boring and your restricted to the same town the whole game. Aside from the ending and maybe one more event, it really doesn't seem like DA2 will have an effect on DA3, and DA:O has very little to do with DA2
