Hey there!
According to the developers Fallout 4 will come with a Steam DRM if you buy the boxed version.
Now last time when I bought the German CE of Fallout NV that one was a big disappointment. Not just that this version was cut, the voice acting was also poorly done, starting right at character creation.
The worst part of it: The German Version didn鈥檛 even allow you to swap to English Voice overs. It was completely limited to German ones.
Back then I also asked Steam if it was possible to swap the key to the international one (I speak German but I don鈥檛 live there), but of course they denied it as it basically were two different games (Uncut Version-> All languages including German, Cut Version-> Limited to German)
So I am wondering if the same will happen with Fallout 4. Will it be cut? Will the language be forced to German?
