I love the origin system, in fact I fell in love with it when I was doing my first playthrough of Arcanum: Of Steamworks and Magick Obscura
I could have made a character, sure, but there were several premade characters with interesting backgrounds whose life I could totally reshapse through playing them.
I still remember my run with Merik Luggerton, who was originally a pit fighter who escaped poverty and ended up on the zeppelin in hopes of a better future.
And damn it, I gave it to him, I even changed his life's entire trajectory, swearing off physical violence and turning him into a great healer and wizard.

I loved roleplaying as that guy, and if Larian wants to give me the pleasure of something similar I will gladly take it, in fact the game would be poorer without this feature.
