Why this games are so unknown?

[FreundHein]

I'm from Germany, too, and all the local stores here (i.e. Saturn, Media Markt, Real) offer Penumbra. Where were you searching for it?

Big magazines like GameStar haven't rated Penumbra well and just had small articles about it, so that might also be a cause for it being widely unknown here. Although I bought Black Plague just because of that article.
