Kingdom Hearts III took its time to come out. I remember that when Kingdom Hearts II came out I was about 18 years old, now I'm 31... But I think it's safe to say that it was worth it, and in a big way.
On this video we can see a comparison between Twilight Town from Kingdom Hearts II and the same town in KHIII. I believe that the footage form KHII was taken from an enhanced version, because it looks a lot better from the version I played all those years ago.
Besides the graphics upgrade you can see a lot more details and I mean a lot! On the latter version you can see people walking down the streets, chilling out on rooftops and even watching a movie. So far one of my favorite thing on this game is the amount of detail added to every corner.

I'm liking this game a lot! I think I'm progressing pretty slow, but that is because I want to be able to enjoy it and just take my time to finish it.
