You know how, no matter what way your character is alligned, any hostile NPCs that spot you start saying "engaging FL blah blah blah"? Is there any way to make them react to your faction tag or to your fitted ID [like they do to contrabrand ,say] so that they say "engaging Junker" or whatever....? I have heard radio chatter during NPC on NPC fights where they say "engaging whoever" so presumably the recordings already exist and it would not require voice acting to implement.
I don't think its possible to do without access to the source code- they don't run a script to determine who you are, as far as I know, if its a human they say "freelancer" if it isn't they go through the other stuff. Convincing the AI to treat people like NPCs might work (and fix the annoying "let's gang-rape the human" tendencies in battle) but guard tags, new faction tags, and untagged people would cause... issues.
The whole reason they say; "Engaging Freelancer ###" is so that a player can hear it and respond. When NPCs target other NPCs, they do not say "Engaging ******" but a completely different line altogether. As the Spam-junkie Sovereign (:P) said, it is determined on whether your a human player, or another NPC.
And sarcasm is the lowest form of wit.......since your comment is also unoriginal and most of your post repetition of what "the spam junkie Sovereign" provided above in a polite and helpful fashion , well.......irony and all that.
