I'm not sure it actually is a positive feature. People think it is, but the games that actually feature it in some regard (say, Age of Decadence talker routes) have had a lot of detractors. There are things the Codex likes theoretically, but then reacts to in an adverse way.
I liked the ratio of dialogue/walking to combat in Dead Man's Switch, I'm imagining Torment will be comparable but with more freedomsssssssssss.
The last time I checked it out, AoD's talking routes were go here, spend time in menus, go there, spend time in menus. It lacked the walking-around-looting-containers-and-discovering-side-quests aspect that people enjoy in Fallout and Torment that will no doubt be present in New Torment.
