I'm not quite sure what you mean. But I'll try to answer.
1) There is a german version
Like most french action-adventures (Little Big Adventure, Fade to black, Inquisition) BGE has a setup that lets you chooose what kind of language do you want the game to run in, so there is an universal version for the most popular languages.
No matter where you buy the game, it will have german language ver built in.
2) It is not censored
The version of BGE is not censored in any way in the german version. BGE refers to terrifying events from WW2 (some Halacaust reference), but there are no nazi in BGE and no extreme graphical violence, so there is nothing to be censored.
