It would have actually been an interesting plot point that Terra decided to/was told to use Corridors of Darkness instead of Light and did so without any protection, thus leading to his fall into Darkness. Unfortunately, if they use bikes instead of Corridors, this would not work so well. :\
I agree completely. When I saw it and everyone commented on it being the Keyblade, I was hoping it was more just something Jumba had built for Ventus to use... D:
A clear sign that Nomura doesn't exactly have the best interests for the KH series especially for the fans.
One way how fans could do a better job than Nomura and SE.
