I bought the game via steam with a german account, hoping to play the english version.

The game does not start if you select "english" as game language ("The game is currently not available...").
If you select "german" (and wait for the additional 2gigs of speech to be downloaded), it does start.

To be clear: I am aware that the german version is most certainly censored (graphics). I do not want you to reverse this (although I don't like it all that much), but give me the possibility to hear and read the much better original english instead of badly translated german.

So, Bethesda or Steam - please get the multilanguage version to work. It was marketed as multilanguage and it is not.

It is not a bug. It's written in steam, that german low-violence version is german only.
