my character was on the negotiation side and I'm not salty because I don't approach RP as a thing that you're supposed to win. Also as others have pointed out, the entire negotiation plan does happen. It fails, but it happens and we get to play it out. It gets a bunch of people trapped on the enemy ship. That's having an influence. I don't understand what would make you happy short of the aliens just agreeing to whatever negotiation was thrown at them and fucking off into space, which is the most boring outcome possible.
