The people that say the main storyline may get confusing are the exact same people that skip through npc dialogue, text and cutscenes. And i suppose having played 1.0 helps a little too since it's the backstory, but still. They did a pretty good job to explain what happened back there and what caused the current world to be what it is five years later.
