Why this games are so unknown?

[Googolplex]

The games from Frictional Games are in my country (germany) very unknown.
You can't buy Penumbra in our shops (only Amazon).
Nobody has heared of it before.

Why it is?
Penumbra is the once real horror-game.
Better than Doom, FEAR, Silent Hill, Resident Evil or Dead Space.

Why this games are not avaiable in germany?
There's no publisher for it?

I think that will be the same with Amnesia.
Frictional Games would get money and we in germany would get the game.
Why there is a big problem?

Its not difficult to translate the games in different languages to sell it around of the world.
That makes game more successful.

I love Penumbra and Amnesia but I hate games in english language.
And I would not have a download-version because there are problems to install coming patches (if any).

what do you mean for?
