Depends on the RPG really. It bothers me less in party based RPGs as you build up a relationship with the characters around you and I kind of end up living vicariously through them. If it's just me I need more if the game wants me to engage with the story.Is that not a major part of an RPG?
Just done a bit of reading around and you get to choose one of three backstories for V which will shape how people react to you so think Dragon Age Origins, other than that there are a blank slate.
CDPR could end up writing around the issues I have with this way of storytelling but that doesn't stop me having concerns.
