This post contains entirely predictable spoilers for the Sith Warrior and Sith Inquisitor stories in The Old Republic.
In both the Sith Inquisitor and Sith Warrior stories in TOR, there comes a point where your master betrays you. You survive the betrayal and ultimately defeat your master. This seems like a very traditional part of being Sith.
Except that's not quite how the Sith tradition goes. The apprentice is the one who betrays her master, not the other way around.
In the class stories, the betrayal is flipped. This is because the game cannot force the player to take action, to betray her master first. If you're playing Light Side, you might choose to be loyal. If the master forces you to take an unpalatable action, you might do it anyways if you are Dark Side.
Well, obviously the game could just not give you a choice. At point X, you betray your master, and that's that. But most players would be greatly unhappy with that.
Can a story-based game push the player into taking proactive actions? Or is the player always reacting?
