Witcher franchise...

[abaris]

All that being said, PofE does look intriguing even though it is (or at least is presented as) a linear RPG and I may have to give it a try down the road.

It is intriguing. And it has a linear story, but with many side quests that aren't fetch and carry. It also recognizes the player's advancement and behavior in the world, as opposed to Elder Scroll titles.

I don't know what you mean with non linear story other than sandbox. Of course they al have a plot that doesn't change.
