I for one really loved how Bioware were able to voice Commander Shephard in the Mass Effect series.
I think ME1&2 strength comes from more then just VO. They put a lot of effort into directing the shots - from camera angles, composition, background sets. You know, using basic visual language, instead of awkward closeups at digital models. Witcher3 succeeded as well - I remember analyzing facial reaction of a small quest NPC and realizing how much work was put into every conversation.
I think the main thing that people are forgetting is that this RPG is quite unique in that it provides MULTIPLAYER functionality.
Not at all! My best time with Divinity was in Coop. I can see it being a boon when playing with randoms, but if I play with my close friend I like communicating. Reading our lines to each other and roleplaying was lots of fun... especially as I took care to create a character which would clash with my friend's character constantly. I never liked coop games which don't require constant communication. Still, I prefer board games for socializing over computer games anyway.
