No mention of the main entries yet?

I agree that BBS is the best. Best gameplay clearly, and for a prequel it really had a nice story and tied things together. I'm almost shocked at how well it fits into the rest of the series. I'm actually more excited about a potential BBS2 than KH3.

Second would go to Kingdom Hearts 2, because I liked the addition of the forms and some of the worlds were a lot cooler, like Mulan. Also the addition of Organization XIII and the nobodies added a nice dimension to the plot.

Third would be the original Kingdom Hearts. It was a great idea and story. The handheld spinoffs were great, but they lack the epic adventurous nature of the first entry.
