Just got done doing brand new playthrough of my "canon storyline" for both DAO and DA2 (actually just finished the Meridith battle 20 minutes ago, lol) just to serve as a refresher for the arrival of DAI.
I may try and do a second Hawke character (coming off from the story of my second DAO character, the ruthless Dwarf Noble) but I may not - I find that I tend to only like the Hawke character if I play the character in a very specific persona (a male mage with a diplomatic/sarcastic personality, who romances Merril, has Carver in the templars, and sides with the mages at the end), unlike in either DAO or the Mass Effect series where I can play various Wardens and Shepards with unique and different personalities with no problem.
