It gives you a button to fly through text you ' ve seen in previous playthroughs . It ' s much more than multiple endings to one story . Each branch reveals pieces of a larger picture . I don ' t think of it as replaying so much as nonlinear reading , a concept that the sequels take to another level . Once you know the full story and get to read the true ending , it ' s mind blowing . Plus , it really doesn ' t take that long . I got through all the endings of the first game without a guide in around 20 hours . For perspective , that ' s about half the length of a 3 D Zelda game or 14 the length of a Xenoblade game . I ' m telling you all this because I LOVE the Zero Escape series and can ' t recommend it enough , and I remember from my first playthrough that just playing to a single ending didn ' t even hint at the level of satisfaction I got from completing the full game .
