ME:A has a very nice UX improvement over the previous ME games: dialogue options which you have already read are a different shade. This is very helpful, since I have wasted a lot of time in the previous games redoing dialogue because I couldn't remember from the blurb whether I'd already used it. For example, (4) here is an as-yet-unvisited option, whereas (1), (3), (7) and (9) have been done:
However, this brings up a new problem: it's possible that a given dialogue option may result in a different dialogue further down the storyline. Does such a case exist? If yes, does the dialogue option change back to the "unread" display?
Best Answer
Probably not.
Based on my 100 or so hours in the game, where I selected many dialogue options two and on occasion three times, sometimes on purpose but mostly by accident, I don't recall ever getting a different conversation.
I also don't recall ever seeing a previously grayed out option turn back to white, however they will sometimes be replaced with a new option in the same location.
