I was doubtful at first, but I see more and more potential with this. Having run away is actually kind of cool. As much as I enjoyed DA:O, I felt all my characters had a similar "tough guy" or "military guy" personality. Sort of similar to Shepard actually. I would have liked to have seen a bit more variety in the kind of personalities you could show.
For example, a rouge character might have more of roguish personality, and be inclined to run when the odds are against them, and strike when a better opportunity presents itself. I could see a more sly Hawke escaping some goonish darkspawn, or some other threat, as he/she deftly avoids capture while chased.
Or a mage newly discovering their powers running from the idea of being locked up in the tower by the chantry, all while avoiding darkspawn. This could in fact be a more frightened and flighty character who is desperate and confused. As the story progresses, the magic wielding Hawke could gain confidence with aptitude in spell casting, and slowly become a sure and capable mage by then end.
What I'm getting at, is that the escape or running away can open up great potential for a character arc. Someone who grows and learns and changes, as opposed to someone who's a tough guy from the start.
I have high hopes. Lets see what happens.
