To me BBS had what KH1 had, Structure. Thats the thing that to me makes a KH game a KH game. The Story blends well into the overall game, worlds effect the plot. The gameplay system is creative and fast paced, but still feels more KH1 than 2. You have to think when using abilities, not just mashing X. The characters are new, and make the game seem more interesting and make me actually want to know what happens to them. The worlds are fun and not too over the top or don't fit, for example Port Royal in KH2. They actually work in the story, like the home worlds of the 3 Princess of Heart. Neverland seemed like the world i wanted to see in KH1 and for improving it in BBS, thats a plus. Deep Space was interesting, and allowed for a Lilo & Stitch world to return for a future KH title. Disney Town was fun and i still go back their to level up and play some mini-games once in a while. The Difficulty wasn't that hard, but i still enjoyed going to the worlds and not being too concerned about being stuck on a boss for like a week. Kingdom Hearts Birth By Sleep is definitely better than KH2 and is just even with the original Kingdom Hearts. I give it a 5/5 for being just as good as the game that started this series.
