@cherub1000: ignore that guy, he clearly only did one ending. Once you "finish" the game for the first time you get to play as 9s without spoiling too much he has a different side to the same story and new gameplay mechanic and once you do his bit you get the 3rd part of the story which is just amazing (that alone took me over 10 hours). But then after that there is plenty of secrets and collectibles to find in the game. I've put over 70 hours so far and I'm still far from finishing everything.
