@Prima Junta and @Maylander: I am still uncomfortable with the idea that nuclear weapons might be trivialised in the next Fallout game for the sake of the retro science fiction setting, whereas previous Fallouts took more of a thinking man's approach regarding the consequences of using them, but I agree that realism can not be the deciding argument here. Unfortunately, whether it fits the setting or not, complaining about it when the game is about to be finished will almost certainly achieve nothing, since at that point the main priority will likely be to remove bugs.
@Alrik Fassbauer: 'Geck' indeed is a word for 'dandy' in germany - 'dude' does not convey the same negative connotations as far as I know - and as you said, it is mostly extinct, occasionally appearing in classic literature, e.g. 'Nathan der Weise' by G. E. Lessing <== wisenheimer comment of the day
