Also, sometimes I do things in-game (doesn't have to be Dragon Age) and I'm like "ARRRRGH I DID THAT BECAUSE OF THIS INFORMATION IN THE PREVIOUS ACT BUT I FEEL A MIGHTY NEED TO EXPLAIN MYSELF I DON'T NORMALLY PUNCH KITTENS BUT I HAD TO BECAUSE THIS IS THE ARCHKITTEN". So an opportunity to clarify might be quite nice.
I'm looking forward to such a feature myself.
Like in DAO, I got the impression that the game kinda assumed I wanted revenge against Bhelen.
I didn't, I just didn't think Orzammar would be safe in his hands (even though we agreed on many policies).
Had I had the opportunity I'd have helped him find some other, humbler purpose in life, away from the political world that had corrupted him so horribly (my character may have been just the teeny weeniest in denial about his little brother).
Killing him was one of the most depressing parts of the entire game for me. And it breaks my heart even more to think that none of those motivations will be recorded in history like that, it'll just be another depressing tale of brother killing brother.
