Sad that dragon age itself heavily dropped their own origin system. It was amazing. Dark urge is definitely something in between, larian created an origin character and removed the companion from the game. If they give you the "mistra cursed" origin and remove gale from the game it would be quite similar.
But I don't agree that they are "just pre-gen" characters, not in the videogame genre at least. They have their own plots, they have some special interactions and sometimes unique mechanics.
A pre-gen character makes me think about the pre-gen that pathfinders games offers you, just a meaningless random pick of race and class.
