Looking at some in my own collection, how about Valkyria Chronicles, Divinity or Dishonoured series, South Park, or the more minimalist Cthulhu Saves the World? All good stories (and the last two are immensely funny)
I also noticed that Planescape Torment has been remastered and released on Steam. IIRC that is recognised as one of the greatest RPGs ever, much on the strength of its story-writing.
