In previous Mass Effect titles, dialogue options were tied to a morality system that would shape Commander Shepard's personality. This allowed players to have different outcomes and experiences depending on their choices throughout the game. However, this won't be the case with Mass Effect: Andromeda, as the game will offer a dialogue system that's more about "agreeing and disagreeing" than moral choices.
Speaking to the Official Xbox Magazine, director Mac Walters has provided some details on new dialogue system and explains why he thinks that this change is for the better.
So, Paragon and Renegade is gone. The reason they're gone is because they felt very Shepard --- they were very tied to the Shepard character, so they didn't really make sense if we weren't going to have Shepard as our protagonist.
What we have now is based more around agreeing and disagreeing. The reason I like that is because in the trilogy it's like, 'I'm gonna play Paragon,' and then you know which way you're moving the stick on every conversation. You don't have to think about it, because you're just going to hit Paragon every time.
With agree and disagree it changes by the circumstance and it changes by the character you're talking to, so you have to actually be more engaged in what's going on, to know if you're going to do that.
We've added in four tones and we'll talk a little more in the future, but they basically allow other types of characters to express them[selves] in one of four different ways, and sometimes one of two different ways. And I think that gets back to that more traditional role-playing sort of feeling which is less about 'Do I want to be good or bad,' and more about 'How do I want to express myself?'.
Mass Effect: Andromeda releases on the 21st of March in North America and on the 23rd of March in Europe.
