Gabelvampir: I think Fallout 1 is only censored because GOG's policy is to distribute its games with the latest patches, and the latest Fallout 1 patch made the European censorship international. At least that's what I've heard.
Nope, it's cencored because it's the version of the game Interplay provided to all DD services and is available in it's physical Fallout Trilogy as well. You can easily turn it to fully uncencored US version by downloading
TeamX's Semi-Official Fallout v.1.2.1 patch (fallup121rc3.7z, also needed for their other patches to work).
Here's the full readme and here's what it does for EU/GOG version of the game:
UK and EU users

* Children animation is bundled with the patch and enabled in the game engine.
No additional installation of children patch required.

changed to "You ass!". Just like in the US patch. (razor.msg)
