Kingdom Hearts 2 was a great game. I reviewed it below. It took me 25 hours to complete, in total. Levels are skippable (I didn't do Little Mermaid, Winnie the Pooh, or the 2nd part of Lion King, although I am going back. ) I just thought I'd let you know that, so that, If you want to go to every level, go there BEFORE going to "The World That Never Was". Once your there, there's no going back.
