Can we please stop placing CD Projekt on a freaking pedestal. Sure they have done SOME things right but they are NOT perfect by a long shot.
First off, this. CD Projekt has made a couple of solid RPGs that, quite frankly, weren't revolutionary by any means. They have good policies regarding patching and post-launch support, but both Witcher games also released in pretty awful, buggy states. TW2 specifically pulled the same sort of ending trickery that people often complain about BioWare doing, where they claimed there were going to be tons of different endings and then there ended up being one with some minor variations. Quite frankly, I really don't see them as being much better or worse than BioWare.
Secondly, I really wouldn't be surprised if a lot of this stuff specifically got cut because of things like racial choices. For as small of a demographic plays anything but humans (in DAO I believe it was something like 20% of players didn't play humans), it causes a tremendous amount of additional work. It also may have been a deliberate choice to focus on more of a traditional BioWare experience combined with a new, open-world structure rather than a completely new and untested gameplay style of a weird combo of Dragon Age and XCOM.
