Disco Elysium, which I haven't gotten around to playing yet so I have no personal opinion, is the only contender I can think of.
The only other game I can think of with that level of narrative craft is the Marathon series, which isn't an RPG, but rather an FPS.
I'm kind of surprised Marathon 4 hasn't been kickstarted yet. There is definitely a whole lot of money on the table there, as the System Shock remake proves.
