"His preferences" have nothing whatsoever to do with whether or not swearing is realistic. I don't care if there's any swearing at all nor do I care whether people are OK with the thought that there might be swearing in this game. In case you haven't noticed, the one and only point I'm arguing on is whether or not swearing is realistic.
Some people swear a lot. Therefore swearing is realistic
Some people don't swear at all. Therefore not swearing is realistic
Both statements are true. Therefore, arguing that one is valid and the other is not is pointless
There ARE people who go through life with little or no swearing. There are ALSO people who go through life with a lot of swearing. Unless somebody's swearing history disqualifies them from a spot, then I think any mature human can agree that it's realistic to assume that somebody who cusses is going to be on our ship in this game. If you were trying to make a point here then you failed miserably.
I don't think the point here is expelling all swearing from the game so much as "How can it be avoided or at least minimized?"
"Crossing into another galaxy" changes how people talk amongst themselves......how exactly? So Mass Effect has a sci-fi setting? And? It's always taken pride in it's above average dialogue, writing and ability to make characters in a videogame seem like, wait for it.............REAL people. If you hardly think that "no swearing isn't realistic" holds any water with regards to this franchise then I'm afraid I'm starting to get the impression that you hardly think at all.
Actually as I said before, if different races are going to be living and working that closely together, it's entirely possible that they'll adopt words from each others' languages. Including swear words.
But the point was if you're going to complain about lack of swearing as being unrealistic, I could point at some other things about the setting that are even less so, even taking into account things like eezo
