Okay well to be honest, I personally prefer Bethesda, but I think the guy arguing Bioware did a better job... So I say BIOWARE for the win on that one.
The reason I prefer Bethesda from a role playing perspective, is that I look at role playing from the tabletop RPG perspective, and in a tabletop RPG the DM finds a way to get from the characters back stories to a place where they all meet, throws one or two encounters their way, to allow for character bonding, and then says.... okay now what do you do? and from there the characters get to move the story along through their actions JUST AS MUCH as the DM does when he/she throws various characters, items, locations your way.
