I don't see lots of reasons why what would work for translations from other languages shouldn't work for Japanese. You don't see much people saying Sultan instead of Emperor, Vizir instead of Prime Minister, Khan instead of Commander, is unacceptable in translations and only the (ironically) literal translation of the title/honorific is acceptable. As long as it's done in moderation and where it's appropriate to do so (and not stuff like Elizabeth-sama in something about England) it shouldn't cause allergic reactions, the way Japanese characters in the backgrounds do for 4Kids.
Chrono Trigger does not take place in japan but in a fantasy world, so your argument falls apart.
That game's whole setting and story got changed and not for the better,
Who even cares of the story for a game like Contra, seriously ? Are you seriously telling me you'll be playing a game of this genre for its story ?
That game was even more censored than what NoA's censors mandated,
The north American release of Contra wasn't any tiny bit censored, unless I'm mistaken.
Castlevania games and countless Amiga games with copious amounts of gore and dismembermen
Castlevania games do not display violence against humans being but against mostly undead monsters, and the european version just copied the American censorship where applicable. Germany probably relaxed their laws eventually.
I don't think it's very rewarding to play a game with missing text or cutscenes supposed to reward the playe
There is no missing text or cutscenes, in the original Contra there is almost zero text and custcenes exept the "game over" title.
You seem to be mentioning the scenes added to the Japanese release, which was made after the US release. Those are also not present in the original arcade game. They were never meant to be there, they were just added for the Japanese FC version and only that version.
Speaking about that, I wonder whether the original arcade Contra was allowed to be released in Germany censored, uncensored, or not released at all.
EDIT : Here is a longplay of the original, arcade Contra game
, on which the NES game is based. The arcade came with no manual obviously (except perhaps a manual for installing the board in a cabinet and how use switches, things like that). Please tell me where you see any story in this game.
EDIT2 : This is pure speculation, but my guess is that Contra's difficulties to be released in Germany was not only about violence, but because of the omnipresent of the red falcon symbol, which looks incredibly similar to the reichsadler
