With regard to the Witcher series... I am just now playing through it, having finished the original a few months ago and now nearing completion of the Roche playthrough in W2. While W1, even after EE, felt very unpolished and not altogether coherent, it had little sparks of brilliance in the storytelling and characters. Having moved onto the second game, it's like a completely different studio took it an ran with it. While the combat is still clunky, it's a refreshing take on RPGs, where the core cast of characters are people you actually care about, the quests all feel like they drive narrative or character development (the lack of fetch quests is particularly wonderful), and the story doesn't feel like it gets derailed for sidequesting (something BioWare games are particularly prone to). There is the odd difficulty with dialogue, but the characters/dialogue/plot is mature and doesn't shy away from that. More importantly, while W1 had some "save the world" elements common to BioWare games, in W2 Geralt is a much more believable character; he is a Witcher who happens to be trapped in events of a much larger scale and provides some small measure of influence on them, rather than a Hero who is going to Save The World. In particular, the regular occurrence of choices for which there is no good outcome, and frequently not even a "lesser of the evils" outcome, is incredibly refreshing. Instead of morality being a simple black/white system, its a function of "pick in which direction you'd rather see the world go to ****." While that can be a bit irritating in the short term, when you think about it its quite brilliant compared to some of the competitors. Geralt is a fish caught in a raging flood; while he can swim generally to one side or another, he's not escaping the general torrential movement downstream.
I'm really looking forward to W3 when I finish the Iorveth playthrough.
Where I think BioWare has managed to continue to eclipse CDPR is in blending RPG storytelling and combat. ME1 had a painful uncompelling combat system; the evolution in ME2 and 3 made the game a joy to play in actual combat as well, and while W2 is more intense and immersive in combat than W1, it's still pretty clunky. Andromeda looks like its going to improve on ME3 again.
