I played two of their games and they handled it differently.
Bound by Flames was older, and the dialogue option was similar to what you see on bioware’s Older wheels with less choices (two was normal). There was a lot of autodialogues. The character had her own personality, and you could not impact it. Choices were practical not to change your char’s personality. Your major choice in the game was one thing that changed character dramatically.
In Technomancer there was a bit more options, but they were worded in the third person, like “compliment her appearance” “say she is brave” etc. Then Zachariah took it away with his dialogue lines. I think Zachariah had a bit more flexibility in his personality depending on his choices, but not as dramatic a difference as between Renegade and Paragon.
If it is like previous games, I think it is most comparable to Inquisition.
Everyone is voiced, yes.
Hope this helps.
