In a perfect world, I could manage a short and to the point answer. Alas, alas...
thanks for all the answers ^^.
i loved breaking morrigan out of her shell too, though sometimes she randomly went back to "bitchy asshole" mode because i focused everything on being friendly with her for the first 2 story missions.
Yelling at the quarian council was my personal favorite ^^, mostly because of my unhealthy interest in quarian everything.
regarding the novel vs. in game question, i mean it more as a "do you project yourself on the character" sort of thing.
For example, I would never ever act like sarcastic Hawke, but I enjoy playing him/her regardless. I am still immersed in the world, and whatnot, but the character's action are not my own. So similar to reading a novel, or watching a particularly good movie where you get to write the plot as you go along.
Others I know project heavily onto the characters. When they describe gameplay they say "I did" or "I decided to" or "Anders betrayed ME", their characters are either personas of themselves or how they'd actually act. They directly take the place of the character.
@StilleNacht: Ooh, I see. In that case... yes and no. Yes, as in I say "I chose to" and the like when discussing the games, because it's easier to talk about the games that way. But no, because even if I am the player who at the end of the day make all the decisions, I try to choose the ones that the character I'm playing would do, not what I would do.
