i took a look at the kh2 ultimania page on khinsider and it says that each world will take around 8 hours to beat and since there is twice as many worlds that kh wich means about 224 hours just to complete all the worlds and plus there is cutscenes and gummi ship flight. and there is also 3 hours before the kh2 logo even shows up. ITS GOING TO TAKE FOREVER!!!! but i'm going to deal with it cause its worth it, besides the more time we play the more surprises and the more fun
