Which Penumbra Should I play first?

[BrooksyFC]

If you really want to enjoy the story, you better off doing it in order cause they all link. I've only played Overture and now playing Black Plague, both very scary games. In some ways better than Amnesia. More puzzles and stealth elements. I know that Overture and Black Plague are linked (I won't spoil anything) not sure about Requiem, but I know that pretty much puzzles and nothing else. Still has good atmosphere from what I've been told.

So go...

1) Overture
2) Black Plague
3) Requiem
