If it were a Squenix park, I'd like to see a ride where there's a giant Musashi (a fake one mind you), and you sit down in his sword and he spins like crazy (like that sword attack he has in the first game :P) That would be cool, though extraordinarily messed up

Aero could be a a very fast spinning ride as well.

And then the Highwind could be like a swinging ship ride or something. Meh.
