Male Hawke does a phenomenal job with the "comedian" dialogue options; I highly suggest you try it
@OP I just beat DA2 last night (Male Warrior) and I enjoyed it a lot. Recycled environments aside, the game was pretty nice to look at and fun to travel through, and the combat was substantially improved. What really sold me on the game was the characters and the overall story, and Bioware didn't disappoint me there. The party banter is phenomenal (I'm pretty sure I heard at least 2-3 dozen conversations between my squad of Anders, Merril and Varric), and it's fun to see them change as the story progresses.
The game did lose a bit of steam in Act 3 though, with some truly perplexing story decisions (Why were the mages attacking me when I opposed Meredith at every turn?) Also, Orsino resorting to blood magic was just stupid. The actual Act 3 story was quite good though, with a heavy politically charged atmosphere and some great voice acting.
