Do you prefer Paragon/Renegade dialogue or DAI-esque dialogue?

You assume that everyone has played DAI.....

Dai or MEA type of dialogue system. Paragon/renegade was good at the time but limiting. Good or bad was obvious. Now you don't know what is gonna happen. I like the whole gray theme goin on.

DAI, but as a side note I'd like to be able to see the current approval rating for each of my companions (if that is even a thing in MEA).

Par/Ren for me. Yes, it's more simplistic but it's also easier to get the best ending.
Pure Par run just makes you feel like a hero with a lot of friends.
Pure Ren run makes you feel like a monster.

I enjoyed the par/ren system but I think DA:I does a better job with the dialogue wheel. Still, it's slightly sad to see the par/ren system go. It felt like a staple for the Mass Effect Trilogy. But change is sometimes a good thing and I'm excited to see the new and improved dialogue wheel.

I was really underwhelmed with the options in DAI. They were usually all so... scholarly. It was tough to ever pick an "intimidate" option that wasn't just "FUCK YOU AND TIME TO DIE". They all felt paragon by default, just said in different ways.

I think there are more advantages of a system similar to Dragon Age over what they did with paragon/renegade. A lot of the time when I tried to get my Shepard to go for the bottom right instead of the top right option it generally felt to be a more extreme change of view that didn't really fit a character, with Dragon Age you don't have the extremes, but it allowed me to feel there were more options to what I would pick to say.

One thing that always annoyed me with Mass Effect is I generally felt punished by not always picking the same type of response for I would lose out in some way later on. With Mass Effect 1 it would impact several quests and the showdown with Wrex. In Mass Effect 2 it was the Miranda/Jack argument or the Tali/Legion argument. While in Mass Effect 3 if it wasn't high enough you wouldn't have all the dialogue options with The Illusive Man. If it was something either then not picking the one of two different dialogue options it would be one thing, but that is what was limiting final choices I generally just stuck being one extreme or the other.

In reality they are basically the same thing, just with Dragon Age: Inquisition you have more then two types of responses and only a couple will be available at any one time.  I didn't play Inquisition the same way as other BioWare games, but with Dragon Age 2 you would develop a reputation in one of three categories of Diplomatic/Humorous/Aggressive it was just that multiple different dialogue tones impacted those three reputations you could gain.  It did impact NPCs reaction to you, it was just a lot more subtle then Mass Effect and at the same time it impacted more NPCs then Mass Effect did as well.

I definitely hear you. I just felt the overall tone of the choices was rather muted. With Mass Effect you had clear contrasts in tone and style. In DAI, a lot of the choices, while slightly different, really didn't change the outcome. Variety is great, but I still want to feel as if my choices have impact. Fallout 4 was similar where you had multiple choices but they would actually lead to the same consequence. What's the point of even having choices then?

There is definitely an approval system in DAI. You can push companions to leave if you do things absolutely detestable to their sensibilities. It just requires a lot of effort, likely because BioWare didn't want to face backlash from players accidentally making too many companions leave.

I definitely agree that some of the decisions in Mass Effect just felt out of character at times. They were either way too nice or way too mean. It just felt out of place and was a bit uncharacteristic, which was pretty jarring at the time when making the choice.

I definitely agree that locking later decisions in the game behind arbitrary paragon/renegade choices was poor design choice. Because of this, I missed the opportunity to convince TIM to blow his brains out several times. I had to go back through the entire game just to make sure I absolutely made the paragon choice every single time. That type of approach also forces players to either pick paragon or renegade every single time, which actually removes player choice.

I definitely agree that from a personal taste perspective, DAI is the better solution for customization. Paragon/Renegade is incredibly limiting and one dimensional, even if the choices could be very satisfying because BioWare was working with two extremes. It's harder to get those satisfying outcomes when you have more subtle and nuanced choices, but hopefully BioWare can pull it off.

DA:I.

DA:I's approach to dialogue choices about the only thing the DA series ever did better than Mass Effect.

Dialogue systems like ME1/ME2/DA2 are awful, all they do is turn the protagonist into a caricature. The DAI/MEA system allows the protagonist to act like a believable person who reacts differently based on the situation.

Also good riddance to the charm/intimidate options aka brainwashing
