Bringing the topic back round to interupts....
I liked the interupts in Mass Effect as they added a "flow" to conversations that is missing from the base dialogue. This flow helps conversations feel active and alive as well as providing cool scenes and extra content. I have some issues with them however. The very nature of interupts mean that unless the situation is contextually perfect for the interupt, you really only have a vague idea of what is going to happen. This can be seen as a strength or weakness depending on your viewpoint, but I find it as something that hampers my enjoyment.
Slight spoilers for the Mass Effect Series!
In ME2 the interupts had context problems. You had a general sense of what the interupt would be usually, (I.E. push man out window, shoot robot, hug sad person,) but many times you never really KNEW what your character was going to do.
My biggest example for this is during Miranda's loyalty mission in ME2. In one cutscene you are stopped by a squad of soldiers. The leader of these soldiers approaches you, and starts warning you to back off. In the middle of his sentence, you are given a renegade interupt. Now you do not know what will happen here. I assumed something aggresive would happen, and I assumed my character would probably kill the guy.
I didn't see my character wiping out the entire squad, snapping the leaders neck and blowing up machinery as part of the interupt. That was... Interesting. The event itself was cool, but I was kinda left hanging there with my jaw open. If I had known that as an option normally, I would have been fine with it but that was a very crazy moment!
If Dragon age did this I think they might be able to do it better since they are not tied to the paragon renegade system, but they would still have the context problem. What will happen when that flashing interupt icon appears? What is the intent behind it? Will this interupt make my character do something I don't want to do? will the indecision make me hesitate to choose it, and thus lose out on advantageous content? (Interupts often gave you an advantage in combat, even if just slightly.)
TL;DR
I'm conflicted. I like the flow interupts provide, hate the inherent indecision.
