How do I need to vary my gameplay in order to be able to view all of the different lore and dialog in Dishonored 2?

I just finished my first play through of Dishonored 2, using Corvo as a character and a low-chaos and stealth approach (actually got the Shadow/Clean Hands achievements combo).

I know (reference) that a different character/play style combination changes the outcome from the story.

I have just started a New Game+ play through, this time with Emily and aiming for as high-chaos as possible, but I've noticed that all her dialog (including her personal thoughts and reactions to the game world) seems to be very deadly/aggressive in nature, which made me wonder how deep the play style actually affects the dialog/lore.

My question is: what combination of character and play styles would I need to replay to actually see all the content? And in addition, for those who attempted it, is it worth the effort to experience the impact it has on the general lore?

Solution 1:

Yes, you get different dialogue depending on choice of character and current chaos level, not limited to direct choice consequences - i.e. how you resolve specific objectives and side characters.

The Dust District and Crack in the Slab missions also have more than two final outcomes.

So if you want to see everything you'll need four complete playthroughs, and multiple additional repeats of missions for every permutation of actions.

I suggest that it's not worth it. Most of the major stuff is available on YouTube to have a look at separately.

With regards to lore, the canon events are:

Corvo is turned to stone
Emily is marked by the Outsider
Alexandria Hypatia is cured
Kirin Jindosh is killed
Breanna Ashworth is spared
Aramis Stilton is saved
Duke Abele's double takes his place
Delilah is trapped in her painting
Corvo is reanimated
Overall low chaos
