Honestly with the Mandalorian/Hutt scenario, for a coherent storyline you can just screw the fourth person over. That is a real story, three people taking the one path while the other pouts five feet behind the group and bickers the whole way saying "I told you so." Sometimes you have to be the disgruntled third wheel.
How many times does a game make a choice for you? This is done by cutscenes, but how many times do you kill a boss, only to have him magically live in the cutscene and limp away while you stand there helplessly and watch? How easy would it be to put a bullet through someone's head while they run off in a pre-determined battle? You're in the middle of a small fight, and spot the antagonist sneaking off, while your character preoccupies himself with a few grunts, fully aware of the enemy.
We're always screwed over for the sake of extending a game or driving the story in the way that the creators (or the majority of your group in an MMO's case) desire. It makes it aggravating, but realistic.
