More to the point, if this game is in English, why does it use a German word. It is intended to bring to mind the Nazis, but it doesn't use the way the Nazi's use it. The characters in the game are not required by law to say Heil "their leader" every time they meet one another. By using heil, instead of hail, (or preferably God Save the King), the gamemaker seems to want to bring mind the Nazis but to soften them a little.
1.) There are no Nazis in Parasite Black - Therefore, there are no 'nazis to soften up' - National socialism as a concept does not exist in this world, nor does the Alderian Government hold racial purity views or views of lebensraum or anything close that would identify it with Nazism.
>What the government *is* is a wartime government that has came to be after the uprsurping of a king during a conflict they were losing...
badly. It is jingoistic, desperate, and is increasingly exerting control over its citizens, thus, it *does* have facist elements, but that isn't close to being the same as being a 'Nazi government'
2.) Many characters in-game do not hold a great view of the government, some such as the royal Mage even lamenting the many uncessarily freedoms they've lost and wish for a new government...If I was just waxing fascisms balls, I wouldn't waste time showing them as factional, corrupt, and overly oppresive.
3.) There are purposeful allusions to fascism to show the government isn't good, that's the subtext. For whatever reason, you have taken that to mean 'Author referenced the bad thing therefore author supports the bad thing.'
