My experiences are very much the same. I haven't had my attempts backfire, but every time something comes up, I'm afraid they might. Last night I did a quest to catch a killer. I get there, he claims to be innocent. And for the first time in a Bioware game, I'm... not sure. Could this little tit be lying to me? Or did the guy who sent me lie? Is there a third option?
Edit: And another situation I'd like the stress. This was the first game, ever, that I killed a character begging for their life. But they made it more personal than anything I'd seen before. The character was truly a threat. And I felt I had to. I don't play characters that do what they "had to." But oh god...
The whole Chantry/Mage thing is what I wished DAO was. Dragon Age is supposed to be oppressive to the Mages, but paint that as a necessary evil. DAO didn't really do that, it didn't come across as oppressive, and barely came across as necessary either. DA2 does. You have seemingly good people being threatened with death from Templars. And you have other seemingly good people turning into monsters. It's a recurring theme and not just some little boy who went nuts. Well, it kind of does. Apparently the Templars have Nazis. "The Tranquil solution to the Mage problem." I am not making that up.
I like that there's no central villain (so far). People love to talk about seeing a political plot and that seems to be what the game is so far.
