Honestly I'm in the minority but I prefer DA: II Anders. In Awakening... what was his personality? Besides being a snarker? I found DA: A Anders to be rather nondescript (then again, you could hardly call all of the characters in it 'developed'). Pretty much his only plot line was 'help me, I'm escaping!'

DA: II Anders still had the occasional sarcastic jibe or banter, but it became less and less as Justice began taking over. Was he mopey? Yeah. They could not have hit us quite so full in the face with his angst, but the lighter side is/was there. It's even lampshaded by a banter with Varric in Act 3 where he describes him as 'no longer funny'.

Basically, I didn't mind DA: II Anders at all. He was moody, sure, but overall he was an interesting character.

If Anders does come back, I'd be interested to see where it goes. I would like to see some of the sarcasm come back, if possible, without losing the inherent brokenness of the character.
